Effect of coaxial electromagnetic field on separation density of dense
The process of dense-medium cyclone is simple, but a set of dense-medium system must undertake the clean coal separation control. Additionally, the separation density of the middling coal and gangue should be considered (Wills, 1992). When the raw coal quality changes continuously, satisfying the separation requirement is generally …
