Working Principle

The material to be processed is fed by gravity into the pulverizing chamber. A low-speed grinding rotor forces the material into a vo ex ow path. Individual pa icles of the unground product are centrifugally thrown against the walls of the conical grinding chamber, where they then rise in a spiral path.
The action of the rotor on the walls of the grinding chamber exe s high shear on the product. At initial impact, a large po ion of the product is reduced below the cone ape ure, which is instantly discharged to the mill discharge. The chute is designed to provide maximum free space for the discharged material, thus preventing the possibility of buildup.
A small fraction of the larger unground pa icles continue to travel up the conical walls within the product vortex, further reducing in size in the process. The largest possible eventually reach the top of the vortex where they re-enter the feed stream to repeat the cycle.
