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.

Obviously, the SAG mill is consuming more and the ball mill less power than was predicted by the empirical method, but the overall total is % of the predicted total. Examples. The Hemlo gold project of TeckCorona (1000 mtpd) provides an example of mill sizing using the empirical calculation method alone.
