Wear Characteristics of Large Grinding Balls in an SAG Mill

The wear characteristics of larger than 120 mm-diameter grinding balls used in large semiautogenous (SAG) mills is studied in the present paper. SEM observation on the worn ball surface reveals a severe microcutting process. Abrasion grooves can be found on the overall surface. Moreover persistent

Modification of SAG mill liner shape based on 3-D liner

May 16 2009 · Modification of SAG mill liner shape based on 3-D liner wear profile measurements. they also transmit energy to the mill load and lift the grinding media up. Thus they have a key role in tumbling mills performance It was found that the wear rate of the second half of the mill (17.1 g/t) was smaller than first half (19.1 g/t).

Throughput optimisation in milling circuits

If the mill feed setpoint is changed then the actual feed rate needs to stabilise at the new target in a short period of time. The feed rate setpoint can then be tied into a SAG mill power optimisation strategy. SAG mill discharge control is quite involved due to few interactive variables such as mill discharge sump level classification
