Compare the Benefits of Steel VS Rubber/PolyMet Mill
When are steel liners better than rubber/polymet liners in a SAG mill or Ball Mill? Lets compare! Rubber Liners are better for abrasion grinding ie: cascade action but not for cataract mills. The graph below shows the increased operating cost of rubber and steel liners as the grinding ball size increases. Larger mill, larger ball increases the cost benefit of using steel only mill
