Heavy-media Cyclones for coal cleaning

Like the heavy-media vessels, Heavy-media 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 Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder.

Dense Media Separation (DMS) Plants JXSC Machine

The difference between heavy medium cyclone and regular hydro cyclone is that the medium to be fed is not water but a suspension liquid. After sorting by heavy medium cyclone, heavy minerals and some media are discharged along with the sedimentation port, and light minerals and the rest of the medium are discharged from the overflow port, de

2019-4-10  Dense medium coal preparation is generally classified. Separation of lump coal is usually carried out by a heavy medium separator under gravity and separation of foam coal by a heavy medium cyclone under centrifugal force. Coal washing (1) Coal washing can remove 50%-80% of ash and 30%-40% of total sulfur (or 60%~80% of inorganic sulfur) in coal.

2001-12-1  In the dense medium cyclone, a mixture of medium and raw coal enters tangentially near the top of the cylindrical section, thus forming a strong vortical flow. The refuse/high ash particles move along the wall of the cyclone (due to the centrifugal force) where the velocity is the least and is discharged through the underflow orifice or the spigot.
