If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Figure 1 – Typical reverse configuration ball mill circuit flowsheet. Once the laboratory has completed the size distribution analysis of the ball mill feed (CUF for the standard reverse circuit) and ball mill discharge, the CSE calculation is straightforward. First, choose the 'size of interest' for your circuit.
To illustrate the comparison of the grate discharge Ball Mill to an overflow type of mill we are showing on page 31 several actual case histories of installations where the performance of grate discharge mills versus overflow mills have been proven. In each such test, run for long periods of time, the ore characteristics and size of …

According to the pattern, the residence time thresholds beyond which overfilling a ball mill is likely to occur were defined. For a ball mill with an internal diameter smaller than 5.9 m, the volume-based residence time threshold is set at 2 min; and for a ball mill larger than 5.9 m in diameter, the threshold is set at 1 min. In addition to ...
The ball load and pulp load have a significant influence on the ball mill product size and production capacity. To improve the circuit performance at industrial scale these variables must be ...
Ball mill in operation: 7.9 m (26 ft) diameter ball mills ... The latter type is fitted with discharge grates between the cylindrical mill body and the discharge trunnion.
