Introduction Rod Mill Used as the primary comminution unit in a grinding circuit. Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser.

Block Mill Rolls. Quality of the wire or rod is decided by these rolls. These rolls demand very high resistance to wear and thermal fatigue. Performances of the rolls are determined in terms of tonnage rolled per pass. Kennametal grades between 12% and 20% binders are preferred. Selection of binder depends on the water quality and discharge.
