Control Feed Size. The particle size of the material entering the ball mill is controlled between 2515 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.

Advantages of this ball grinding mill include: less friction, less energy and more easily activated, because large diameter double row selfaligning roller bearing instead of sliding bearing is used as the main bearing. This ball grinding mill can achieve bigger capacity thanks to larger size of feed inlet and discharge outlet.
