The pelleting process is very complex, and over the years, researchers and industry professionals have evaluated ingredients, conditioning moisture, temperature, and time as well as die specifications. Of these factors, selecting die specifications is still often difficult. There are definitely reasons why die selection is not always a straightforward and easy process. Probably the greatest hurdle to overcome is the cost of a new die; depending on the size and die materials, this could be a $5,000-15,000 decision. If you order the wrong die, it’s not usually something that can be returned. Therefore, the intent of this article is to bring awareness to some of the factors to consider when working with your die supplier.

It is a professional terminology referring to a key part of pellet mill. It can be seen as the mold of pelleting. The structure and quality of matrix largely affect the performance of pellet mill and quality of finished biomass pellets. Matrix is generally made from high hardness alloyed stainless steel. To ensure high finished degree and long service-life, matrix needs to be processed through vacuum heat treatment and precision finishing. Ring Die Pellet Mill is suitable for medium&large pellet production and industrial use.

The raw material used for making fuel pellets is called biomass. Biomass is any living or recently dead material that can be used as fuel.There are a wide range of raw materials which can be made into biomass pellets, including wood sawdust, chips, shavings, branches, logs, palm EFB, palm fiber and stalks, straw, rice husk, peanut shell, sunflower seed shell, bamboo, bagasse, mushrooms residue, cotton residue, grass, cassava residue,etc.
