Grinding in ball mills is an important technological process applied to reduce the size of particles which may have ball mill is its production capacity which is measured in tons of production per hour. (coefficient of reduction), the work index of the material, the mill shaft power and the specific gravity of the material.
It is measured according to the principle that to calculate the grinding work index based on output of each revolution of the mill after the material is ground to a balanced state by the specified mill. This ball mill, also called mill for measuring bond work index, is a key device for measuring grinding work index.

Ball mill Wikipedia. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silies, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals.
SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42'' () in .
The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a ''locked cycle'' test conducted in closed circuit with a laboratory screen.
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...
