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 equilibrium ball mixture was used to investigate the effect of ball size distribution on the selection function whereas the original equipment manufacturer recommended ball mixture was used to validate the model.

A ball mill has a cylindrical rotating mixing vessel, which is partly filled with round balls. These balls must have a larger diameter than the product that is to be grinded. The material of these balls depends on the type of product. The size of the bullets depends on the desired application. Larger balls grind or cut the product and finer ...
