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.

A hammer mill is an impact mill commonly used in pharmaceutical manufacturing for reducing particle size for a variety of drugs. Commercial grade ammonium sulfate was milled as a model powder.

The hammer mill blades are replaceable or can regrind easily if they were worn out. This machine was designed and constructed for crushing locally available grains of maize, sorghum, wheat, barley ...

Our hammer mills reduce dry and semi-moist materials with a minimum amount of fines and caking or plastering within the crusher. They are ideal for granulated and pelletized materials. Hammer mills utilize a central rotating shaft, affixed with several "hammers" on pivots attached to the shaft. As the shaft spins, the hammers are swung via ...
