Principle Of Operation Of A Coal Cyclone

  • Dense Medium Cyclone Principles Portaclone modular coal

      The discard portion of the raw coal (sinks) leaves the cyclone at the spigot, and the clean coal (floats) via the vortex finder The cylindrical section of the cyclone can be extended by the introduction of a barrel section which effectively increases the residence time within the cyclone and can improve the sharpness of separation between the
