Hammer Mills. Hammer mills process the grain using either a series of swinging or stationary steel bars (hammers) to grind the grain. In most hammer mills, the hammers force the grain against a screen until the grain is the desired size and passes through the screen, but newer "screenless" models can use airflow instead of a screen to sort the grain that is the desired size.

This is accomplished by a four step process: 1. Material is fed into the mill in one of many ways, including: hand fed, auger or belt conveyor. 2. Inside the grinding chamber the material is repeatedly struck by flailing ganged hammers which are attached to a shaft that rotates at a very high speed. The material is crushed by a combination of ...
