WhatsApp: +86 18203695377Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
WhatsApp: +86 18203695377Like 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.
