Factors affecting ball mill grinding efficiency

The following factors are studied and applied in traditional ball mills to maximize grinding efficiency. In 1954, it was observed that the grinding efficiency was a function of the diameter of the ball mill in terms of the geometry and speed keys of the mill, and an account of the empirical relationship between the recommended medium size and the mill speed, taking this factor into account, was established. And, mills...
