Pellet mills are unlike grinding mills, in that they combine small materials into a larger, homogeneous mass, rather than break large materials into smaller pieces.
Two cutters are used to cut the pellets free from the outside of the die.
A die, also known as a mold, holds the uncompressed powder in a shaped pocket.
[3] Some platens are heated to speed up the time it takes and improve the overall structure of the pellet.
Animal feed pellets are usually a mixture of dry powdered feedstock, such as flour, sawdust, or grass, and a wet ingredient, such as molasses or steam.
