key factors affecting mill throughput and grinding efficiency: mill speed, ball loading, and liner lifter face angle (angle between the lifter face in contact with a grinding ball and the lifter base). Its central hypothesis is that face angle drives a ball mill's grinding efficiency and throughput independently of the type of liner used.

measure both ball load and pulp slurry positions inside a running mill. The main data are provided in terms of toe and shoulder angles. (Figure 6.) The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a
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.
This article shows a case study at the Tropicana Gold mining complex that utilizes penetration rates from blasthole drilling and measurements of the comminution circuit to construct a data-driven, geometallurgical throughput prediction model of the ball mill. Several improvements over a previous publication are shown.

Calculate Ball Mill Grinding Capacity. The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates ...
stirred media mills and high-pressure grinding rolls, ball mills still retain a significant part of their importance in grinding, being widely used from minerals and cement, to chemicals and ceramics. The operation of a ball mill is a capital- and energy-intensive process, so that even mar-ginal improvements in their efficiency result in immense
Jan 01, 2005 Ball-Mill Circuit Operation. Very often in SAG circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sace in grind, the focus shifts to throughput so much that the available ball-mill power is not used to the fullest extent.
