Oct 28, 2021 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 Reasons Nov 01, 2002 In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of

The SAG mill and ball mill original design was reviewed and a change resulted in the application of a gearless drive wrap-around motors on both machines. This immediately delivered energy savings as the units areinherently more efficient in transferring incoming power to the shell of the mill. The use of A recent report by Newmont Asia Pacific summarised significant energy savings at their Jundee operation. Sag/Ball Mill Weight Control (Newmont Jundee Operations) During late 2009 and early 2010 the power draw of the SAG and Ball Mill motors at Jundee was reduced by better managing the SAG and Ball mill weight.
