Get PriceHow Important is the Length of the Grinding Mill to Comminution . The relationship of mill diameter to length is of considerable importance. Rod mills should have a length greater than the diameter to avoid entanglement of rods. The construction of ball mills is different in that the diameter may be larger, equal to, or smaller than the length.
