If the energy to produce new surface by singleparticle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more realistic value of about 15% for the ...

Get Price#### Electric motors monitoring: An alternative to increase the efficiency of ball mills

efficiency of ball mills has focused on the monitoring of the fill level. For a given amount of steel balls, it is not desirable that the mill is too full or too empty of grinding material. If the fill level of ore grinding is low, most of the energy of the steel balls is wasted in impacts between them, leading to low comminution ratios. As the fill level increases, the gaps between the steel ...

In this example, the OWi of the SAG mill was found to be 30% higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions. In contrast, when the SSE75 was calculated, it showed the SAG mill consumed 20% ...

Get Price#### Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...

Get Price#### Grinding Aids for Ball Mills

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill.
