Comparison of energy efficiency between ball mills and …

· Comparison of a laboratory vertical shaft stirred mill with a ball mill, both operated in a virtually closed circuit with a classifier, indicated that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding.

In previous publications, we have described how the size specific energy (SSE) can be calculated to predict the energy required to generate new minus 75 µm material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 µm, clearly we require a finer marker size. If we do this, we also need a way to compare results that use different ...

· The specific energy of grinding is the energy input into the mill related to the mass of material m p. During the tests, the gross torque T and the rotational speed N were measured at the shaft. Considering the torque of the empty mill T o (which represents bearings losses, etc.) and the grinding time t , the specific energy E m can be determined by Eq.
