Development of ball mill test for simulation of industrial circuit

Here too, the specific energy consumption estimative was separately investigated for the optimum ball size, mill rotating speed and lifted/smooth mill shell. Tests 1 and 3 indicated that 72% and 69% of the critical speed resulted in best results, as well as Tests 1 and 4 indicated that 38 mm and 30 mm optimum ball size resulted in the best results for such an aspect.

Ball Mills

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.
