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.

The primary function of a hammer mill in a feed mill setting is to reduce the size of the raw materials, such as corn, wheat, and soybeans, into smaller pieces. This makes the material easier to handle and mix with other ingredients in the feed mill. The hammermill consists of a rotating shaft with a series of hammers attached to it.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

Hammermills accomplish size reduction by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has little or no momentum (low kinetic energy), whereas the hammer tip is travelling at a minimum of 16,000 feet per minute (4,880 m/min) and perhaps in excess of 23,000 feet per minute (7,015 m/min) (high kinetic energy).
