IntroductionReduction RatioRod Mill CapacityRod Mill Capacity ProblemsRod Mill Power Draft1. Used as the primary comminution unit in a grinding circuit. 2. Rods are placed parallel along the length of the rod mill. 3. Rods are 150mm shorter than the mill length. 4. Breakage occurs more from cascading than cateracting. 5. The product size distribution is narrower than a ball mill but significantly coarser. 6. Most are overflow discharge type. 7. Length-to-diameter= 1.4 to 2.3. 8. Mill length = 7 meters.在millopsmunity.uaf.edu上查看更多信息## Ball Mill Rod Mill With Large Capacity - radiosintjan.be

Tubular Rod Mills. As in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. the mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.
