Quantifying the energy efficiency of fine grinding

Size Specific Energy (SSE) differs by relating the grinding energy to the quantity of new fines generated. For typical circuits that involve AG/SAG, HPGR or ball milling, the generation of -75 µm material (denoted as SSE75) is a suitable marker size with which to benchmark performance because it contains 80% of the surface area generation 1
