  • Dense Medium Cyclone Plant, Coal Washing/Parnaby

    Dense medium cyclones are used for very accurate separation of particles of different density Particles smaller than 05mm are removed from the mixture before it enters the cyclone Magnetite is added to the water/particle mixture to allow precise control of density The dense medium cyclone is mounted at a 15° angle The lighter particles (coal) come out the upper end and the heavier

  • Coal dense medium separation dynamic and steadystate

    A coal dense medium separation process can benefit substantially from process control provided that a dynamic model for this process is available as was previously developed by the authors for a fine coal dense medium cyclone (DMC) circuit In this paper, the previous model is adapted to a coarse coal DMC circuit and validated over a wider range of operating conditions using real plant data
