Ball Mills an overview ScienceDirect Topics

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D

Addition of pebbles to a ball-mill to improve grinding

01/04/2017· Table 3 is a summary of the preliminary tests (in duplicate) using various proportions of balls and pebbles. The on-line torque measurement was used for early measurement of the power drawn by the mill, so that the grinding time could be calculated, to maintain the same amount of energy for all tests (i.e. assuming a constant grinding efficiency).
