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 m material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 m, clearly we require a finer marker size. If we do this, we also need a way to compare results that use different Get price
