I think in ball mills you can use steel balls which are very resistant to wear rates, but in SAG mills its tricky as the accumulation of small steel balls due to low wear rate in the mill will affect so much your power draw, meaning that your power draw will be high whilst grinding efficiency is reduced as in SAG mills you need larger steel balls, this will cause a reduction in throughput.
Dec 12, 20190183;32;Even the dual medium quenched low chromium alloy steel lining can be used for more than 6 years in coal mills in power plants, about 2 years in cement mills, and more than 8 months in iron ore mills. The hardness of the liner and the grinding ball should be above HRC50.
Low Chromium Alloy. ModelLow chromium alloy grinding ball Weight0.11~8.74kg Surface hardness45 HRC Application rangeIt is widely used in powder preparation and superfine deep processing of industries, such as building materials, mine, chemical engineering, ceramic material, papermaking, magnetic materials.
The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills. The increased frequency is due to the Increase in charge volume (35 40% versus 5 10%), higher mill speeds, and the larger number of balls per unit charge weight.
