Ball Mills - an overview ScienceDirect Topics

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.

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

The Difference Structure between Overflow Rod Mill

The rotating speed and the medium charge ratio of the overflow rod mill are low. The particle size of the feeding ore is 25~30mm. If it is oversize, the steel bar will be skew and the make the steel bar bend and break in the operation. Meanwhile, the oversize material will make the gap between the bars big.
