Dense medium cyclones for coal washing. Free Online Library

Sep 01, 1991· Feed coal Even though the dense medium cyclones can treat coal down to 150 microns efficiently, the usual practice in coal washeries is to feed only +0.5m coal. The reasons for this are: * 0.5mm is the smallest particle size which can be easily rinsed on screens without excessive loss of magnetite and without blinding the screens.

It is also non-fouling, which means that even if small amounts
