### calculation charge of grinding ball in cement mill

how to estimate the wear rate for Ball mill. Dec 08 2009· Re how to estimate the wear rate for Ball mill Hey Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials With new balls sample of given size can be weighed before and after grinding a given tonnage and assuming uniform wear per unit of ball surface the total charge wear can In any mill the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is seen to be Kick s law.
