Quantifying the energy efficiency of fine grinding ...

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% ...

Ball Mills

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part loed between them (Fig. ). Such a ball mill body is expedient because efficiency is appreciably increased. Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge ...

5 Ways To Improve Grinding Efficiency Of Ball Mills

· According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be considered.

Electric motors monitoring: An alternative to increase the ...

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 ...
