Quantifying the energy efficiency of fine grinding circuits -

14/05/2020  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 marker sizes. Benchmarking energy efficiency requires three measurements: comminution power, rock throughput and the resulting size reduction. The first two
