Tube mill. Tube mills consist of revolving cylinders, with a number of hard balls which act as the grinding media. Tube mills differ from ball mills essentially in having an inlet for material feed and an outlet for the ground material. Hence, tube mills have larger length to diameter ratio (≈3:1) as compared to ball mills (≈1.5:1).

A ball mill is a drum-grinding 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.
