    KREBS Cyclones Heavymedia Cyclones for Cleaning Coal

    Like the heavymedia vessels Heavymedia Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation the Heavymedia Cyclone forces the lighter solids to its centre where the slurry transports them upward and through the vortex finder.
