HAMMER MILL Principle: The hammer mill operates on the principle of impact between rapidly moving hammer mounted on a rotor and the powder material. 11Fig: Hammer mill 12. Working: The hammers are allowed to be in continuous motion(8000- 15000 rpm) the feed material is placed into the hopper, whiles hammers are in continuous motion.

thyssenkrupp Ring Hammer Mills – also known as Ring Granulators – are mainly used for crushing of coal in thermal power stations. The material is crushed initially by impact with ring hammers and in a further step by rolling compression between the ring hammers and screen cage plates before it is squeezed through the screen slots.

Hammer Mill Working Principle. The hammermill, fundamentally, is a simple mechanism. The “orthodox” machine comprises a box-like frame, or housing, a centrally disposed, horizontal-shaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing.

A hammer mill has the advantage that the rotatable hammers will recoil backwardly if the hammer cannot break the material on impact. One significant problem with hammer mills is the wear of the hammers over a relatively short period of operation in reducing “dirty” products which include materials such as nails, dirt, sand, metal, and the like.
