Quantifying the energy efficiency of fine grinding circuits

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 ...

Correspondingly, the grinding efficiency of the earth mill will also increase, but at the same time, the energy consumption will also increase. However, if the filling rate of the steel ball is too high, the motion state of the steel ball will easily change, which will reduce the impact on large-particle materials.
