Sag mills, on the other hand, rarely approach the efficiency of a ball mill.Breakage mechanisms are not nearly so well defined, and while it is possible to influence breakage rates in the mill by changes in mill speed, ball load, and feed size distribution, manipulation of these variables will often fail to produce a power efficient circuit.Get Latest Price
