Mounted horizontally or vertically, the hammers swing freely around the shaft to crush aggregate material fed into the pulverizing chamber from above. It is then progressively crushed between the milling elements (mantle and concaves), finally exiting the pulverizing chamber at the bottom through the influence of gravity.

Material is fed into the mill, typically by gravity. Inside the grinding chamber, the material is repeatedly struck by flailing ganged hammers which are attached to a shaft that rotates at a specified speed. The material is crushed by a combination of hammer blows, collision with the walls of the grinding chamber and particle on particle impacts.

Hammer Mills. Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill's grinding chamber. The material is ...

The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper.

Among those styles, the functionality of a hammer mill remains basically the same: Material is fed into a grinding chamber. Contact with moving hammers, and interior mill components reduce the material's size. Material remains in the hammer mill's grinding chamber until it is able to pass through a screen or grate with certain size openings.
