Hammers or Knives to grind or crush by impacting materials at high speeds. Rotations per minute (rpm) typically vary from 1,800 to 3,600 rpm. Many designs allow the hammers or knives to rotate clockwise or counterclockwise for more even wear. They come in varying styles or shapes for use in grinding specific materials.

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.

Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
