  • Practical operational aspects of DM cyclone separation

    A dense medium cyclone performs a separation within a separation. Classification of the medium solids (separation via size) occurs; therefore the medium solids will separate to a certain degree. The feed, overflow and underflow will have different medium densities. Factors affecting differentials are medium viscosity/stability.

  • Mineral Processing Dense Media Separation Bond

    Process description DMS cyclone plants. The DMS process involves the mixing of a pre prepared ore stream with a dense medium of selected specific gravity (SG) in a mixing box and passing this mixture through a dense medium cyclone (DM cyclone). It is here that separation of the high and low SG fractions of the ore occurs.

  • Dense Medium Separation Hydrocyclone Separator

    DM Cyclone Operation. The reason for the near horizontal position is that, in the vertical position, the gravitational pull on the dense medium results in a slumping of the medium toward the apex, which pinches the air core. Under a slumping condition, the separation efficiency would be very sensitive to inlet pressure and medium viscosity.
