continuous ball mills. In an experiment conducted using a wet laboratory continuous ball mill filled with pebbles, cylinders and balls of equivalent volume and a 95% calcite feed combined with a 5% quartz, ball load, density and shape were varied. It was shown that decreasing the ball load by by weight also decreased the residence time by 40%.

A ball mill is a drumgrinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.

Ball Mills: Ball mills are cylindrical devices used to grind materials such as chemicals, ores, and paints. The cylinder is filled with a grinding medium (such as steel balls) and the material to be ground is added to the mill. The rotation of the cylinder causes the grinding medium to cascade, creating an impact and grinding the material.
