The principle is similar to that of the hammer mill. A rotating beater presses material through a fixed classifier or mill screen. However, there are key differences: the beater rotates more slowly (typically 1/10th of the speed of a hammer mill), flat bars replace hammers, thus material is pushed or ground through the mill screen.
