How Can I calculate new ball size and weight desing for ball mill
4.See the availability of roller press in comparision with the mill. 3.If the performance of roller press will be too good the u can run the mill only @24-26% loading with a very good out put and @ low specific energy. 4.Tonnage of grinding media u can calculate on the basis of dia.length and the filling degree of mill. Thanks . Pankaj. Reply
