Hammer mill Impact mills are similar in construction and principal to HSI and VSI crushers. Impact mills are used to pulverize feed material by impact against a surface or a bed of feed material. The feed material may be propelled by gravity or by a rotating impeller or rotor. The impellers or rotors can be vertically or horizontally orientated.

A] Hammer Mill Working Principle and Main Components. The process of size reduction (for feed material) is carried out by rectangular pieces of hardened steel that rotate inside the chamber at a high speed, striking the material to be milled with a powerful force. These radially swinging hammers (from the turning central shaft) help crush/grind ...

Pneumatic Discharge Hammer Mills The grinding mechanism of this group is quite similar to the gravity discharge hammer mills. However, the pneumatic mills typically use a thinner hammer and the interior wall of the grinding chamber features a ribbed liner plate. This plate has a washboard effect on the material, and works in unison
