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

Dec 08, 2009  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.
