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.
