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.
