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.Since the feed rate of second stage mills in the Aoshan concentrator was 400 t/h, the total grinding unit consumption of second and third stage ball mills was 13 kWh/t. (3) P = η P 0 where P is the active power of the ball mill (kW); η is the power factor (80% in this paper); P 0 is the installed power of the ball mill (kW).

The ball mills, the second stage grinding equipment, are 7.9m in diameter and 13.6m long, each with two 7800 kW motors. 52 magnetic separators are used in each of the processing lines. Two concentrate thickeners, each 45 metres in diameter and four …8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
