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.

Throughput optimisation in milling circuits

The feed rate setpoint can then be tied into a SAG mill power optimisation strategy. SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump.

New sensor system for ball mill control.

 · Several approaches to ball mill control are known. A typical problem is that direct control by feedback from a size analysis of the ground product, for example, is not satisfactory because of the transport time ( often 20 - 25 minutes between feed and discharge ) of the material being ground and because of the lack of a continuously acting device for measuring the size range of the product.

Addition of pebbles to a ball-mill to improve grinding …

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19-75 µm). Batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble mixtures.
