This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.

In general the ball mills are utilized to grind material 1 4 inch and better, 20 to 75 microns down to the particle size. Also, to have excellent efficiency with the ball mills, they must be functioned in closed circuit system. Some of the classifiers for assorting the discharge from ball mills are screens, cyclones and air-classifiers.Environment and that of the classification system . A ball mill circuit has two efficiencies because it has two main functions • The grinding of coarse particles and, • The removal of the fine particles to make room for grind-ing coarse particles in the ball mill. The overall efficiency of the ball mill circuit is therefore comprised of.
