    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 be estimated. More simply and quite adequate is to keep a record of material ground and of charge added periodically to cover a given level of mill
