How To Reduce The Abrasion Of Steel Balls In Ball Mills

In grinding operation, the consumption of ball mill steel ball is very large, about 10 times more than that of ball mill liner. In order to make up for the loss of steel ball and keep the ball load particle size constant in the ball mill, it is necessary to add steel ball regularly according to a certain proportion.

mass during abrasion, the primary driver of mass loss in ore particles was the applied load. It was found that the mass loss rate gkJ was directly proportional to the applied load during the steady state phase of the rocks response to the abrasion mechanism. This introduced the possibility of establishing an abrasion index for rock particles.

Mill Charge An Overview Sciencedirect Topics

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height or depth of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
