Top 5 product specific milling technologies used in

How ball mills work. A ball mill grinds material by rotating a cylinder filled with media (typically metallic or ceramic balls) mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.

Overflow VS Grate Discharge Ball or Mill Why Retrofit

In the case of ball mills these are the overflow type, semi grate or intermediate pulp level discharge, and the true grate discharge. A general statement can be made that the closer the discharge is to the periphery of the shell, the quicker the material will pass through and less overgrinding will take place.
