The simplest way to describe the concept of size reduction is to look at the industrial hammer mill model: Hammer mills operate on the basic principle that most materials will crush, shatter or pulverize upon impact. This is accomplished by a simple four step process: Material is fed into the mill, typically by gravity.

In a dualstage hammer mill, there are really three phases of size reduction, due to what is known as the attrition zone. The attrition zone is the area created between the top rotor and bottom rotor of a dual stage hammer mill. Materials pass through the initial mill and screen arrangement and are then directed toward the secondary mill chamber.
