Comparative comminution efficiencies of rotary, stirred and …
The rotary ball mill (RBM, Faure, France) consists of a ball-filled drum fixed on two rollers that impact a rotational movement to the drum. The milling media are steel balls of three diameters (25, 20 and 15 mm) combined in a 1:1:1 ratio by mass. The milling media fill one third of the total volume of the drum.Web

A guide to maximising ball mill circuit classification system
In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 per cent of the particles in the mill are 'coarse' and that 77.1 per cent of the mill power is being used 'effectively'. Conversely, 100-77.1, or 22.9 per cent of the mill contents are 'fine' and are being ...Web
