Established for 20 years, the business – this recent IMD online member – serves a range of industries including automotive; metal stamping, plastic mould die makers and tool designers. JLS supports its customers with high precision and quality products, in step with impressive timeline delivery, and competitive pricing and always aims to be highly responsive to product delivery in step with any specifically submitted customer drawings 

accuracy

The company always imports quality materials to ensure its products achieve accuracy and meet demanded  close tolerances in all respects.  These carefully selected quality products includes the certified tungsten carbide products obtained from reputable, expert companies.  The JLS tungsten carbide used in its projects is always of  specific hardness and is thus outstanding in terms of its wear durability and corrosion resistance These factors are ‘a must’ in order to meet  specific testing client demand. Here below the JLS experts highlights in its online blog  aspects of the important Punch and die process……..

cost effective 

Nowadays, Punching is usually the most cost effective method for creating holes in sheet metal materials from medium to high production volumes. The process, when a specially shaped punch is used to create multiple usable parts from a sheet of material is known as blanking. In metal forging applications the work is often punched while hot, and this is called hot punching. Slugging is the punching in which punch is finished as soon as the metal fracture is complete and metal is not removed, but still held in hole. 

shearing forces 

Punch and die is often made of tungsten carbide (tungsten carbide punches and dies) or hardened steel. A die is located on the opposite side of the work piece and supports the material around the perimeter of the hole and helps to localise the shearing forces for a cleaner edge.

There is a small amount of clearance between the punch and the die to stop the punch from sticking in the die and so less force is needed to make the hole. The amount of clearance needed depends on the thickness, with thicker materials requiring more clearance, but the clearance is always greater than the thickness of the work piece. 

hardness 

The clearance also depends on the hardness of the work piece. The punch press forces the punch through a work piece, producing a hole that has a diameter equivalent to the punch, or slightly smaller after the punch is removed. All ductile materials stretch to some extent during punching which often causes the punch to stick in the work piece. In this case, the punch must be physically pulled back out of the hole while the work is supported from the punch side, and this process is known as stripping. The hole walls will show burnished area, rollover, and die break and must often be further processed. The slug from the hole falls through the die into some sort of container to either dispose of the slug or recycle it.

JSS to the fore.. as portable ‘pre-fab-type’ housing demand Worldwide continues to rise and rise…

Our latest IMD member member is Guangzhou Jinzhao Steel Structure Engineering Co. Ltd.  Founded in 2014, JSS is a China-based manufacturer and supplier of well-styled, affordable weather-resistant container houses  portable bathrooms and ‘sandwich’ panels for portable house-building. These products all have exceptional insulation properties. 

With the development focus for the future on quality ‘prefab’ container houses and facilities, Jinzhao Steel Structures continues to build and win customer trust and increase brand recognition Worldwide..Check out more below on ‘portable housing’ compliments of the JSS blog…

more popular 

Pre-fabricated homes, such as JSS are developing have been around for many years, but they are gaining more and more popularity these days. According to Global Industry Analysts, Inc., the global shipments for pre-fabricated homes are expected to reach 1.1 million units by the end of this year. As the global population continues to rise, the housing supply finds it hard to meet the demand and therefore, housing prices continue to go up. 

construction delays

Prefab homes can help deal with this problem for a variety of reasons. These homes can be built fast, meaning there are fewer chances of budget increase and construction delays. There are various types of prefab homes and one of them is a manufactured home. A prefab home and a manufactured home are sometimes confused with each other. This is not necessarily wrong, as you can call a manufactured home a prefab.  However, a prefab home is not always a manufactured one and can be a different type. To settle the confusion, this post below is going to show the difference between the two so you can make an informed decision when choosing which you might want for your home.

What Is a Prefab Home?

According to a post from Now from Nationwide, a prefabricated home or prefab home is “a house that is built in sections at a factory and assembled once its components are delivered to your property.”

This means that the components of a prefab home are built in a factory-like setting. The finished products are then transported to their intended location where they are assembled by the builder.

Different Types of Prefab Homes

Prefab Homes  – these can be built differently, depending on your needs and the style you want for your home. These are the different types of prefab homes:

Kit Homes – a common preference for people who want to build their home firsthand. This type of prefab homes are pre-cut and transported to your building site inside a kit. The kit will include all the components you will need to build your home along with the instructions on how to build it.

Panellised Homes – these are built in panels in the factory and most of the interior work is finished on the building site. These home packages usually come with roof trusses, exterior walls, and floor systems. In this type, the floor and foundation are laid first. You can hire building contractors to build the interior walls and install electricity and plumbing.

Modular  Homes – a great example of type is a shipping container house. The construction method of this type of prefab home provides astounding adaptability. Modular homes can be made of a single unit or they can be joined together in any layout you prefer. As the name implies, modular homes are created out of pre-assembled modules. They have their large sections completed in the factory before arriving at their intended location. Interior fittings, such as stairs, doors, closets, plumbing, and electricity, are all built into sections in the factory.

Manufactured Homes are another type of prefab home. This type of home is built entirely inside a factory. …for more ..check it out at the JSS blog …visit here ….. https://www.jjchouses.com/blog

‘Flying high’ with their double offset ‘butterfly’ valves – that’s Huamei Machinery….

New IM online member, Ninjin Huamei Machinery is a professional manufacturer of double offset, high performance, butterfly valves, available in soft seat, metal seat and fire-safe seat designs. The advanced sealing technologies of these products ensures reduced seat wear and a highly effective, bi-directional, zero leakage shut off function throughout the full pressure range.

leading the way 

With unique valve-seat design, which equal Flowseal and Bray, the Huamei Machinery company has now become the leading manufacturer of double offset, high-performance butterfly valves throughout China. The business has a CE PED approved foundry and all products are manufactured under an ISO 9001 Quality Assurance Program. This ensures each valve product meets –  and very often exceeds – all and every customer application and performance requirement.

innovation and passion 

Huamei Machinery is totally committed to the needs of customers, and its passion for innovation, product quality and dedication to responsive service will never change. Superior pre-sale & after-sale services are very actively pursued by the business,  and in step with this all contact enquiry messages  are responded to within eight hours by our outstanding sales or technical experts.

What is a (double offset) high performance butterfly valve?

A High-performance butterfly valve is generally made to use on the high-pressure piping system. The high-performance double offset butterfly valve, used in higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear.

benefits 

Huamei high performance butterfly valve offers the high-performance butterfly valves with the low-cost, lightweight benefits of a butterfly valve design. It is ideal for handling water, oil, steam, gas, and slurries.

Huamei high-performance butterfly valves satisfy a wide range of industrial applications. Available in carbon steel or stainless steel, as well as lug and wafer body styles, they can be specified in sizes 2″ through 60″.

Main Product Features 

Double offset/eccentric design with bi-directional bubble-tight shutoff performance, extremely high pressure application than ordinary butterfly valves; Double offset/eccentric configuration with conical angled disc design; Long life durability due to double offset operating principle minimizing seat wear; High pressure application with small torque.

Maximize flow and minimize resistance providing high Cv; Seat available in either Soft (PTFE/RTFE), Metal or Fire Safe; Fast and simple seat replacement. All of soft seats, Metal seats and Fire Safe seats are inter-chageable ; Excellent corrosion resistance and finally internal travel stop design to prevent over travel of the disc, minimizing possible seat damage.

How it works?

The double offset design of the Huamei High-Performance Butterfly Valves assures reduced seat wear and bi-directional, zero leakage shut off throughout the full pressure range.

At the initial point of disc opening, the offset disc produces a cam-like action, pulling the disc from the seat. This cam-like action reduces seat wear and eliminates seat deformation when the disc is in the open position. 

extended service life

When open, the disc does not contact the seat, therefore seat service life is extended and operating torques are reduced. As the valve closes, the cam-like action converts the rotary motion of the disc to a linear type motion to effectively push the disc onto the seat. The wiping action of the disc against the seat prevents undesirable material build-up from slurries or suspended solids.

How Tianhui are equipped with the experience and technical knowhow to provide and produce perfect OEM stainless steel castings

The Tianhui Machine Co  – a new IMD online member – has these days developed and innovated extensively  in order to become one of the leading CNC Machining shops in China. The Company’s customer base spans several countries around the world, including several ‘Fortune 500’ companies, Industry ‘leaders’ and also many small and mid-size businesses. Tianhui have an impressive and highly  pro-active customer service record.

tight tolerances 

Tianhui is equipped with well-selected,  advanced machining equipment, able to  produce  all kinds of small, medium and large concept items to exact shape and tight tolerances. Tianhui has passed ISO9001 quality management certification.  The company has an impressive key expertise at machining stainless steel and alloy steel materials in particular, and the company experts here develop key online information below on their ability and experience to effectively and expertly provide OEM stainless steel casting parts, also highlighting the key steps on producing high quality stainless steel casting parts. …..

Providing OEM stainless steel casting parts through experience and knowhow 

At Tianhui Machine company, we are expert at producing various quality OEM stainless steel casting parts. More than 1/3 of our sales revenue comes from the production of stainless steel castings. and now we are working with several qualified investment casting foundries, to ensure we can produce various customized stainless steel castings according to precise customer need.

very familiar 

As a business, we have rich experience in producing OEM stainless steel casting parts. Before we established  Tianhui Machine company, our company leader and key engineers had all worked in an investment casting foundry. Therefore, they were very familiar with the casting process and  have in-depth technical communication and understanding with all foundry matters . We have now been producing stainless steel castings for decades. We know which foundry is suitable for various products, and we are an active buyer of foundries, Therefore we can get price-competitive castings compared to many other machining shops or trading companies.

entire process

Because we are familiar with both casting and machining process, our engineers are deeply involved in the entire casting process, from the tooling design to gate place, We work with the producing foundry to determine these technical details and all precision data . This ensures that we get best accurate qualified casting parts for further machining.

How to apply best processes to produce quality OEM stainless steel casting parts?

Our customers only need to provide drawings, 3D drawings or samples, and we can start producing stainless steel castings.

The first step is to produce a silica sol casting mould. The mould is usually made of aluminum. Now, it is very cheap to make a casting mould. For customers who co-operate with us for the first time, we are also willing to share mould costs with customers.

The second step is to produce stainless steel castings by our supplier. Modern casting process such as investment castingcan produce near-net-shape casting parts. The precision casting minimize material waste and machining cost, usually only need machining few place to get tight tolerance

The third step is machining We generally machine the contact surfaces, sealing surfaces, threads of castings and every place that requires very tight tolerances.

Tianhui work with 100+ qualified local suppliers. The company are totally integrated in terms of  its numerous processes – Casting, Forging, Machining, Inspection, Heat treatment and Surface treatment. – which in turn enables the business to be able to complete totally finished machined parts specific to individual customer requirement.

How does your health and well-being measure up ..have you got it taped?

There’s more then meets the eye when it comes to something of an everyday item like the humble tape measure it seems… a new IMD  online member of ours – Wintape Co Ltd from China  – has a hugely successful business making tape measures … 

specialises 

Founded in 1998, Wintape is a leading manufacturer of tape measure products.The business specialises in producing and supplying  a wide range of tape measure products. These include a traditional ‘tailor’s tape measure, steel and paper tape measures, one for animals and a body tape measure.Also, developed by the business are more specialist products – retractable, diameter, laser, measuring wheel, badge reel, and also a spirit level and even a measure belt clip. The custom printed tape measure is also a lead, in demand product of the business

thought provoking 

All that being said, a visit to the Wintape web site will reveal some more facts that are highly thought provoking.  A tape to measure your health is what they highlight. They point out that the measurement of your body may reflect potential illness. You can know things about your body first by a simple daily body measurement. You can, it is suggested primarily judge your health by measuring four particular sites on your body …. .

First ‘measure up’… the neck 

Do you feel the neck get tightened when you are wearing a shirt? An expert at Framingham Heart Study points out that a person who gets a thick neck, though his waist circumference is in normal range, he may have higher blood sugar, which will lead heart disease.

Therefore, measuring your neck circumference helps to recognize your upper body fat distribution. Upper body fat is closely related to heart disease risk. A thickening neck causes less High density cholesterol, which will block the transmission of cholesterol to liver for metabolism. The optimal threshold neck circumference of men should less than 38 cm and women should less than 35 cm. Generally speaking, circumference of neck should be equal to that of calf. Every 3cm increased in neck circumference, accordingly, high density cholesterol inside your body may average decline 0.12 mmol/L. The figure on women is 0.15 mmol/L When measuring neck circumference, tester should stand straight and keep both arms naturally drooping. Mouth should slightly open to relax muscle tension. Place the tape measure on the seventh cervical vertebra ( the most protruding part of your nape) and below your larynx ( the thinnest part of your neck

Next… the waist 

Heart disease risk is not only relates to weight, but the site body fat lies in. Compared to systemic obesity, people with abdominal obesity have higher possibility to suffer cardiovascular diseases. Fat accumulated in the abdomen is more harmful to that in the legs and hips. Oversized waist indicates exceeding visceral fat. It may cause diabetes, high blood pressure, dyslipidemia,  coronary heart disease,stroke and other diseases.

 For males, they may easy to suffer colorectal cancer. Research finds out that abdominal obese people have 40% higher risk to suffer cardiovascular diseases than other people. Middle aged men with a pot belly might at a greater risk for a sudden death, and the risk will increase if the belly gets bloating.Many people mistook the waistband as waist circumference. But the standard measuring site is above your hip bone and the feet should be apart in the distance of 30-40cm. 

You can go online and check the waist hip ratio and the head too if you wish … and let’s hope you measure up!!!!!

The technology…. the expertise….the research… and the knowhow – its all in a cup of coffee …. AFPAK style!

The AFPAK Company of China specialises in designing developing  coffee packaging and machines – a further new member of IMD online this week. The business has an innovative, experienced, research and development team, which has produced technology and expertise to ensure that the current range of AFPAK machines are of effective operation and design and also durable and up to date in all respects in terms of performance, usage and client customer requirement.

innovation 

Attentive after sales service, backed by the quality, durability and technological innovation delivered through its products, has enabled AFPAK to develop a high reputation for its customer satisfaction coupled with the originality and cost effectiveness of its products.  Below the experts at AFPAK highlight key features of their hugely successful  K-cup filling machine… 

The K-Cup filling machine is a machine used in packaging food, beverage, and any other product. The products are to be filled into a K-cup, thus the name K-cup filling machine. A K-cup, on the other hand, is a single serve coffee pod, the latest version of its kind. A K-cup filling machine has six stations in order to fill a K-cup. These stations have their own functions:

Cup-Placement Station  – At the cup-placement station, the K-cups are placed in their designated stack. Once the K-cup filling machine is turned on, the K-cups will be placed on the cup ring which is located on the rotary type table. 

Filling Station – At the filling station, the K-cup will be filled with the material which is correctly measured for the required quantity in each cup. This is possible with the help of a spool valve. The materials are stored in a hopper which is placed at the top of the spool valve. Furthermore, the position of a cup is detected by sensors. If the cup is not detected, then no material will be placed as well. The filling process is automatic and the accuracy is around 0.5 – 1%. Usually, a K-cup filling machine can contain up to 30 litres of materials.

Lid Placement Station – Once the K-cups are filled, they will be then transferred into the rotary turret going to the lid placement station. The lids are taken by vacuum cup from the magazine. After which, the lid will be gently placed in the cup. Optionally, the lid can also be placed and snapped in the ready cup.

Sealing Station – After placing the lid of the K-cup, it will be then sealed using heat sealing or hot punch. This process is very quick and simple.

Data Printing Station – Right after sealing the lid of the K-cup, it will then be printed with on either at the top of the lid or at the bottom part of the cup. Usually, printing is done using heat. The details that are usually printed in a K-cup includes the manufacturing date, batch number, and expiry date.

Discharge Station –  The sixth and the last station in the process of filling and sealing a K-cup is the discharge station. In this station, the sealed and printed K-cups will be discharged into a conveyor belt which usually measures 1 metre long for collection. Finally, the filled K-cups will be packed into cartons, ready to be delivered.

‘Homing-in’ on Henan K– steel structures and ‘sandwich’ panel for all kind of buildings of strength, style and practicality…

Our latest IMD sign up is a ‘house builder’ of a rather unique and very different kind of way as we know here it in the UK. They are Henan K-home Steel Structure Co Ltd. Established in 2007, they are a business in the design, fabrication and installation of steel structures and specialised  ‘sandwich’ panels, which are mainly used in the ‘construction’ of numerous types of container-styled, modular varied type buildings and residential houses. The business manufactures and supplies these container house’-type structures as modular ‘homes’ and also produces portable building constructions for use as factory site offices and also portable classrooms at schools and universities ..and much more….

sourced 

The core technology for production of these structures is the HenanK polyurethane composite board product originally sourced  from Italy. HenanK has produced their own particular composite board since 2010. The HenanK core PIR  Polyisocyanurate ‘sandwich’ panel has the scale and strength for it to be totally suitable for various roof and wall additions to the likes of a large-size factory. This board product is composed of four sections or parts. On the top and bottom, the material used is best quality steel.  It has good insulation and high heat resistance performance. It is high strength, has an  attractive appearance. It is also fast assembly, fire-proof, heat-proof, and flame retardant  

whole-use buildings 

The company’s product range is not only the base construction panels’, but actually whole-use buildings, such as an OEM Prefab House-  a portable, modular, temporary solution for workers who need to live on a construction site,away from the city; The ‘Container’ House – a building for a business needing an additional office, canteen, or rest room. There are also Light Steel building units; A Light Steel Structure ‘House’ and ‘Villa’ structures and also a non-standard ‘Design’ House. There are in fact numerous other specifically required and specified Steel Structure building-type structures 

installation

The HenanK business supports all its product range ‘buildings’ with an expert full-support installation service. Here below we can include an expert online presentation from the company highlighting the illustrative advantages of one of their example buildings – the K-home Container House.

Presentation information 1 – Both our base and roof purlin strength factors are increased. Other suppliers use 10pcs but ours are 14pcs.The main frame of the product is pressed by a special steel plate, and the side panels have special insulation fillers, which can play the role of heat insulation, sound insulation, cold protection and fire prevention. ; Sand paint or galvanized paint is used which greatly improves the corrosion resistance of the components.

The overall service life of the box house can reach more than 20 years. It even has excellent earthquake resistance (level 8) and wind resistance (level 11). The product weighs about 2.5 tons, which is convenient and feasible for lifting.

Presentation information 2. – We modified the water drain system.Each column is designed and equipped with 4 water drain pipes and we design substantial water drain channels for the roof structures, to ensure the house will be totally water-proof.

The drainage system of the container house is composed of four water channels and downpipes. When it rains, the rainwater on the roof will be collected into the water channel and then flow down through the down-pipe of the corner posts to provide an orderly drainage system to achieve better drainage and easier rainwater collection.

Presentation information -3 Our column and roof, and corner joints are stronger. The house building could be moved very safely and quickly.

The building structure allows for a three floor ‘stack’ and the roof can bear snow up to 1.5m,  The snow load of any roof is individually designed in step with possible to weather conditions depending on the building location. 

Pest controllers RES ..and the historic rodent issues now haunting modern-day London

You may or may not know that the city of London in general has something of an historic ongoing ‘today’  problem with rats and mice, which have thrived as a result of the ever changing human structural advancement in the City over the centuries. So, speculates our latest IMD online recruit the Regional Environmental Services company…..

expertise

RES is an established business that serves the whole of the UK capital city and also surrounding Southern Counties regarding all bird waste/fouling and pest control problems. Their team are specialist surveyors and technicians with considerable expertise in pest control and relating to pest presence. The business belongs to the BPCA which provides continual legislative updates on all aspects of pest control and  relating handling requirement.

CRRU code 

It operates in step with relevant industry codes of practice and progress. It is a compliant with and has a full understanding of the CRRU code of best practice of March 2015  and ensures its field personnel  are always qualified to use and administer rodenticides in accordance with precise practices. All RES staff undergo updating training via specialist seminars where qualification certificates are issued, following post course tests. All technicians receive industry periodicals as a method of update on legislation and varying codes of practice.

obsolete

So, that’s all about RES … now read to get their informed thoughts on  the rats and mice and other pests of London and why they are there.  As mentioned already,  the type and style of structural development in London over the years  has  left in its wake the obsolete foundations of the past, which apparently – suggests  RES –  serves as a ‘thoroughfare’ for rats and mice to go through to the many modern structures – in particular offices and also intensive older-styled apartment development areas.

enticed

The combination of this situation and both rats and mice being enticed in by tasty morsels of food being left in the work environment leads to ever greater numbers of rodent sightings. The numbers of rats and mice accessing any building will vary depending upon circumstance such as rise in water table, seasonal change or construction works, nearby.  All this occurs despite the pest controllers best efforts to entice mice to eat bait or go into traps. Thus any pest control service and system within a building has to be a programme requiring client co-operation to achieve the prime objective of reducing numbers of rats or mice in any particular building.

not prevention 

Focusing on mice, pest control is very much control and could not be considered prevention, especially in the urban environment where there are too many unpreventable factors to offer the latter. Pest control in regard of the customer contractor relationship, has always been a two way street requiring the co-operation of the customer so that the pest controllers expertise is put to good effect.

hand wipes

Due to the modern way of working it is common practice to eat at work stations, with there being very few exceptions to this trend. This can be managed to avoid the availability of food, and food packaging to mice. Crumbs as well as finger smears on desks or inside desk drawers, also packets of food, opened bottles of fruit juice, are not invisible to the sensitive nose of the mouse.  Thus food should never be left in desk drawers. Hand wipes should always be used, following eating and crumbs hand swept into a bag or food container. Bottles of soft drinks should be removed from site at the end of each day, along with all food and food waste.

incontinent 

It is bad enough to have the trauma of seeing a mouse in the office and the revulsion of seeing mouse droppings on a desk, however just as bad if not worse is the unseen urine trails across desks, which are produced by the naturally incontinent mice.There is an infection risk such as salmonella when mice are present, and this is greatly heightened when food is being eaten on a desk, where there have been mice. This is where food or hands come into contact, directly with bacteria infected urine or droppings.

infection 

Mice are less likely to forage and cross desks if no food is present. Our intention is to deal with mice in the building service risers and sub floor areas, where there would be no contact with office staff, thus reducing this risk of infection to virtually zero. We do need help in achieving this by staff having an awareness that there must be a code of hygiene observed, not just for the sake of seeing less mice, but more importantly for the health and safety obligation to themselves, as well as their colleagues.

co-operation

A planned programme should be put into place in order to reduce the issues encountered with mice in a building and should be implemented with the full knowledge and understanding of the building staff that we do require co – operation in regard of food handling. 

effectively trap

This will enable us to effectively trap and bait by focusing the mice on eating what we put down, without the distraction of more tasty morsels nearby.The only long-term method to control rodent populations is to make the area unattractive or inaccessible to them. Eliminate their food sources by keeping desk surfaces, floors, and cabinets clean……so if you work or live in London you perhaps now know what to do 

Lark goes soaring into new fields of success as the years fly by ….

Continuing on a defined mission to innovate and produce the best quality highly energy efficient machineries and related support parts for maximising productivity. – that is Lark Engineering which formed in 1989 as a manufacturer of agriculture machinery. 

soaring 

But, dedicated to progress and expansion, within  five years of start-up saw Lark soaring on its way into numerous new fields – notably the feed machinery market-place. It manufactured its first small 2 H.P. Hammer mill product…. and rest is history and now the business holds two important product patents and has thousands customers across India, Nepal, Bangladesh, Pakistan, South Africa and Bhutan.

partnership 

In moving onwards to further develop these objectives, the business has very successfully extended its role from the narrow confines of a machinery supply company to a solution business of providing through operation, support and expertise, preferred partnership input and guidance to many many high value demanding customers.

combination

The company experts at Lark present below a review reference feed mill production – sometime they suggest  hard to define as it is a combination of so many factors …and often more than a few factors may prove to be not completely as might be expected …read on to review key factors as Lark sees it ..which can definitely affect essential feed mill efficiency and cost effectiveness  …. starting with …..Feed Formulation & Raw material quality…..

a. Fibre

High fiber reduces the rate of production, as fibre is hard to compress into a pellet. But due to natural binders inherent to fiber, a good quality pellet is produced.

b. Fat

The fat content of ingredient or feed aids in increasing production rate but too much fat can affect pellet quality for eg. Too much fat affects pellet durability.

c. Starch

Starch with steam leads to Gelatinization. Gelatinization is defined as the irreversible destruction of the crystalline order in a starch granule so that the surface of every molecule is made accessible to solvents or reactants.  Gelatinized material acts as a binder to produce the desired pellet quality. High starch material with good gelatinization enhances pellet quality.

d. Moisture

Due to high moisture (more than 13 %) in raw material grains; it is difficult to maintain the balance of heat and moisture in the conditioning process. Too high moisture results in roll slippage and too low moisture results in die choking. At low and high moisture operator have to run the pellet mill @ 60 -70 % efficiency.

e. Protein  & Density

Ingredients with high natural protein will plasticize under heat, which will cause good quality pellets. Ingredients or feeds with high density have high production rates. If an ingredient or feed is high in natural protein as well as density, the high production rates and good pellet quality can be expected.At low oil & hard formulations project will give around 80 % of the stated production. 

f. Particle size: If there are bigger granules of maize or other grains the pellet will tend to break at that point after the pellet is formed, resulting in more fines. It is important to maintain uniformity of grinding.

g. Pellet Durability:

Pellet quality is usually expressed as the pellet durability index(PDI) and measured by using a tumbling can device, in which the pellet sample to be tested is first sieved to remove fines, then tumbled in the tumbling can device for a defined period of time. Then after tumbling, we compare the fines produced during tumbling with actual weight – PDI weight of the pellet after tumbling / weight of Pellet before tumbling x 100 . At PDI lower than 88 pellet tends to break during crumbling; producing more fines which rresultin more recycling of feed and low final output. 

h. Die configuration:

Selecting a die as per formulation is very important. As Broiler contain less fibers and more oil %age (soft formulation), which provides better pelleting properties, less frictional load on pellet die. Hence, we can use a compression ratio of 1:12, 1:13 & even more.Using high compression ratio for layer feed may lead to poor die life, die chocking, non-uniform PDI, more power consumption in layer feed, low output, more wear & tear. Using low compression dies in soft broiler formulation may lead to poor PDI (Pellet Durability Index – Pellet Strength). Considering all the above factors using a separate die for both layer & broiler feed is a better and cost-effective solution. Die selections govern approx. 10-15 % in pellet quality & output.

i Key areas are Operational Parameters and ‘skill’: Operational parameters and skill, experience & knowledge of operator plays an important role in plant performance. The same die with similar technical specifications behaves differently in different pellet mills:- 

1. The operator should regularly check the: State of wear on the deflectors and scrapers and also the roll adjustment: To avoid uneven wear on the die and consequently inefficient pelleting; The state of wear of the conditioner paddles: To ensure efficient pre-conditioning;Steam traps and filters: To ensure that no condensate is being passed into the conditioner; Press Roll slippage due to increased moisture content, it leads to die roll over; Observing wearing pattern of dieIt is recommended to change the side of the die (front side – Back side) for more uniform wear, thus setting optimum parameters for different formulations and ingredient qualities.

2. Using spare parts more than their optimum life: Sometimes we use the consumable parts more than their standard life but loose much more in feed quality and life of other parts which directly are related to them. Like for an average die life cycle it is recommended to use 5 pieces (2.5 sets) of roll shells for a better die life and uniform PDI feed quality. Hence using the roll shells & beaters more than recommended life results in great losses in terms of grinding texture, conditioning & pelleting which directly affects pellet strength and PDI; and productivity and above all pellet quality.

3. Steam quality and quantity: Proper steam of good quality is required for better performance of machines and production of quality feed. Steam parameters required are:- Dry Saturated Steam Minimum 9-10 kg/cm2 at the boiler; 2-2.5Kg/Cm2 after PRV; Good & reputed make boiler, Water softener; Proper Steam traps, insulation of steam line and supporting valves.

4. Recipe Management: It will take around 30-40 minutes to change the recipe. It’s better if we run one recipe a shift as it saves time
