Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

2015-11-1 The mill under study has the maximum ball diameter of 40 mm . In this research, the size combinations used were 50 and 40 mm, 40 and 30 mm, 30 and 20 mm and lastly 20 and 15 mm. The maximum ball diameter used was 50 mm since the mill used being a secondary mill, process fairly small particle size and charging bigger balls than that would ...

Ball recirculation inside the ball nut can affect precision and repeatability. As a result, ball nuts are available with a range of pre-load options to reduce or remove the axial play as they rotate around the screw. This allows for better repeatability, for example, because no motion is lost from the clearance in the balls as they reengage.

the rate of grinding in the planetary ball mill is known to be about 100 times greater than that in a tumbling ball mill and about 50 times greater than that in a stirred ball mill2). Another result is given in Fig. 3, from which it is seen that even small glass beads with a low density can be used to grind hard materials

2016-11-18 The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other.
