Each primary mill contains several 4" steel balls that grind the ore as the mills turn. When the ore is reduced to 3/4" or less, it moves out of the mill in a slurry solution. The mill discharge is screened at 1/4" on trommel screens attached to the mill. Ore smaller than 1/4" is pumped in slurry solution to the wet cobber magnetic separator ...

Crushers are the first stage of ore processing. Depending upon the application, power can range from 180 kW (240 HP) to 1200 kW (1600 HP). Rocks as large as 50 cm in diameter are reduced to 15 cm fragments [11, 13] which are then reduced to fine particles in SAG (Semi-Autogenous Grinding) or Ball mills.

Optimization of mill performance by using

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.
