The mill feed material needs to be free of metal pieces. Higher the metal pieces frequent operation of diverting gate and results in feed variation. [8,12,14] Abnormal feed size and distribution may increase the level of vibration and destabilize the mill. Large feed size in any case will reduce the mill production rate. Excess fines in the feed

2023年2月15日 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.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The effect of milling temperature on the amorphization of mechanically alloyed Cu 30 Ta 70 has been investigated in 1991 by Lee et al. [45] In their experiments, they ball-milled the elemental powders of Cu 30 Ta 70 at two different controlled temperatures of 37°C and 200°C for 100 h under the same milling conditions. They realized that ball milling at
