Rod Mill Pass Grinding Demonstration and Seminar

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Effect of Grinding Rod Media Load on Rod Mill Performance Effect on Rod Mill Power Draw. The general relationship between mill power draw and charge level is as shown in Figure 2. As previously discussed, the exact shape of this curve, and the position of the peak, may vary slightly for each particular mill, and depend- on the liner condition.

Grinding Media

ABSTRACT In this paper the effects of flow rate, slurry solid content, and feed size distribution on the rod mill efficiency have been investigated. It is difficult to achieve highest grinding efficiency without sufficient information on operating parameters and their effects on the system. Several experiments were performed on a continuous rod milling circuit. Two flowsheets arrangements were ...

Nov 30, 2015· The flow rate selected at range of 11.5–17 t/h, slurry solid content at range of 27–61%, and feed size distribution at range of 12–30 mm. Results showed that the lowest grinding efficiency was occurred at solid content of 44 wt% and deviation from this optimum amount had positive implications on mill …
