2014-9-9  The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process derived from mass flow balance, a model-based control strategy is proposed. The controller adjusts the density of medium used to enhance separation in the DMC process according to measurements on percentages of different ...

Improving energy efficiency of cyclone circuits in coal ...

2014-4-15  In the dense medium cyclone (DMC) coal beneficiation process, only 25% of the pumped medium are used by the DMC while the other 75% simply flows back the corrected medium tank without being used. Therefore, there is a great opportunity for reducing energy consumption of the DMC coal processing plant by energy-efficient pumping systems.
