    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 less energy to produce final product material than the ball mill.
