Ball Mill & Cyclones - YouTube

In this respect, hydrocyclones are outstanding rougher concentrators. Many operations take advantage of this effect by installing gravity-concentration units in the grinding circuit. Treating a split of the cyclone underflow is perhaps the most common, but ball-mill discharge and cyclone …

High recirculating loads in Ball Mill Circuits - Grinding ...

In my experience, from 200-350% re-circulating is "normal" for a closed circuit ball mill (reverse or direct). The selection of the hydro-cyclones, pumps and piping sizes all go hand in hand with mill sizing selection. Perhaps the most critical thing is selecting the hydro-cyclone vortex finder to ensure the cyclone overflow is clean.
