CALCULATION OF THE GRINDING BALLS

Filling rate of grinding balls for this mill is 25-27 per cent of the total internal volume, i.e. approximately 13-15 tons of grinding balls. The calculation of the average diameter of the grinding ball in the mill showed that it is necessary to use 23.74mm steel grinding balls for maximum effective grinding.

steel ball calculation ball grinding mill

Ball Mill Parameter Selection Calculation Power. 30/08/2019 The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3.
