Grinding Media Wear Rate Calculation in Ball Mill

2017-4-29  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. It then appears that Kick’s law holds true for the ball wear in a rotating mill. The natural tendency is for the small balls to accumulate in the mill

how to estimate the wear rate for Ball mill Page 1 of 10

2009-12-8  Re: how to estimate the wear rate for Ball mill. 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 be estimated.
