A hammermill is one of several types of crushing machines, including impact crushers, jaw crushers, and cone crushers, that is manufactured for the purpose of processing raw materials to reduce them in size. In the crushing industry, there are two types of forces used to reduce the size of materials: impact forces and compression forces.

Hammer Mills: Commonly used in food processing and agricultural industries, hammer mills use hammers attached to a spinning rotor to crush and grind materials into smaller particles. Attrition Mills: These mills utilize the principle of attrition, where particles are ground against each other or against a surface, resulting in size reduction.

Abstract. High speed hammer mills break particles suspended in gas by high velocity impact against a hammer surface. Assuming that the action is comparable to a stream stagnating against a surface, it is shown that the net mill power can be calculated and it is predicted that the power varies approximately proportional to the hammer speed cubed.
