High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

Advantages of this ball grinding mill include: less friction, less energy and more easily activated, because large diameter double row self-aligning 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.
