Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum ,building material, glass, ceramic, steel slag and fly ash, ect. It follows crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
This explains why changing media sizing may produce no effect on circuit performance. Numerous torque mill tests, in addition to the growing plant data base compiled to date, show that media charging near the size that provides highest ball mill grinding efficiency provides a degree of robustness with changing ore grindability.

Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
A ball mill is an important tool in the material handling industry. It is used to grind, blend or even mix materials. There are many tools available to design ball mills. Most use an empirical approach developed from the extensive research into the operation of a ball mill.
Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a.
Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d †“V = 0.40 K ˆšF dB = ball size (cm) F = feed size.
