Factors influencing Pellet Production with flat die pellet mill

Now days, small pellet mill are more and more popular as many families tend to make their own pellets instead of buying pellets at high price. 
1. First, you should be clear about what can be made into pellets, for fuel pellets as an example. Biomass fuel pellets can be made from many organic materials such as wood, paper, cardboard straw, alfalfa, corn husks and stalks, grass clippings, yard wastes and many forest & agricultural wastes. 
2. If the material are too wet, please dry them in the sun to moisture content of about 18%. 
3. For some materials of big size, you should crusher them first with a wood crusher, the best material size for making pellets is about 3-5mm.
Details of Diesel Flat  Die Pellet Mill
1. Introduction.  flat die pellet mill is heavy-duty pellet mill with roller driven design, the flat die pellet mill can process both feed pellets and fuel pellets. For the adjustable pressing ratio of flat die pellet mill design, it can not only make soft wood pellets but also hardwood pellets.
◆The common material for making biomass pellets are leaves, branches, stalks, straws, shells, grass etc.
◆ Feed Pellets: Animal feed was a product of materials such as alfalfa, grain and oil cake,etc.
◆ Moisture content of material: 14%-18%
◆ Material size: less than 5mm.

Factors influencing Pellet Production
Pellet production in real life may come across many problems. How to improve the productivity of pellet press? And what’s the key point in operating pellet machines? Here are many factors affecting the pellet production in industrial production.
1. The Feeding Rate
There is an adjustment that is not well known to have an impact on pellet production,before pelleting,you need to use feed grinder to crush raw materials into powder, That is the rate of feed put into the pellet mil. In fact, adjustment on feed rate and maintaining a consistent feed rate can be the key factors to impact pellet production, even if the raw material is perfectly prepared.
2. Operating Temperatures
Temperature is a key requirement in pellet production. Unless a certain temperature is reached in the pellet mill, natural lignin will not melt. the flat die feed pellet mill is not possible to produce some biomass pellets. For example, wood pellets without sufficient heat. However, if the temperature is too high, this can damage the pellet mill and particular consumables such as the pellet mill dierollers, bearings and seals.
3. Clearance between roller and die 
Another adjustment that can impact heavily on how successfully the pellet mill operates is the distance between the roller and die template. The roller and die are wearing consumable parts, due to the abrasive nature and pressure of compression. The distance set between the roller and die can impact on how much energy the pellet mill uses, the quality of the pellet, pellet mill productivity and the amount of fines produced. Correctly ,setting up the die on a pellet mill will also increase the life of the roller and die, and reduce the cost of changing these consumable parts.
4. Die Template Rotation Speed 
The speeds at which the roller and die turn affect the complex relationships during pellet compression. Some materials require a greater time under compression, and therefore require a slower rotation speed.
5. Die Design and Material Used
Many different forms of metal alloy are used to produce pellet mill die templates. Different metal alloys have specific advantages. Using the correct alloy is critical to reduce wear and increase production. The type of metal used also affects the finish of the die holes. Our flat die pellet machines all adopt high alloy steel to make dies and rollers to lower consumption.
