Pellet mill
From Wikipedia, the free encyclopedia
A pellet mill is a type of mill used to create cylindrical pellets from a mixture of dry powdered feedstock, such as flour, sawdust, or grass, and a wet ingredient, such as molasses or steam. Pellet mills are used in the production of animal feeds, and of wood and grass fuel pellets for use in a pellet stove.
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. In this way, pellet mills are similar to extruders. Feedstocks for pellet mills can sometimes break down and then re-form, or polymerize, under the extreme heat and pressure of the pellet mill.
