Check Details The Working Principle of Hammer Mills (Stepbystep Guide) A hammer mill is an essential machine in the pharmaceutical and food processing industries. You can use it to crush, pulverize, shred, grind and reduce material to suitable sizes. Even though there are many types of hammer mills, the working principle is still the same.

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

A typical hammer mill consists of a hopper, horizontal shaft, rotor, hardened steel or stainlesssteel hammers, and removable. Hammers are usually made of hardened steel or stainless steel with an impact surface of extremely abrasive material such as haystellite and carbaloy; however, pharmaceutical use hammers are made of stainless steel SS316.
