Ball Mill Explained - saVRee

An electric motor is used to rotate the ball mill. As the ball mill rotates, the balls 'stick' to the inner surface of the drum due to the centrifugal force created within the drum. At a certain angle, the weight of the balls overcomes the centrifugal force holding them against the drum and they begin to tumble back to the centre line of ...

Ball Mill - an overview | ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. 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 Effect of Ball Size Diameter on Milling Performance

A laboratory size ball mill of diameter 30 cm was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively as shown in Figure 1. Quartz was the material used to run experiments, and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm Abstract
