DENSITY IN THE GRINDING CIRCUIT WHITEPAPER
produced by the ball mill, so the cyclone overflow allows a lot of these middle size particles to escape the grinding circuit. This results in a decrease of material that the ball mill would have to grind, which lowers its efficiency. Also, unwanted particle sizes are leaving the grinding circuit to next process stages.

Quantifying the energy efficiency of fine grinding circuits
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 and energy is proportional to surface area generation 2.
