This process is used for the efficient separation of fine coals or mineral particles of between 1mm and 100 microns.
The raw material is deslimed and then diluted before being fed into the top of the top of the twin spirals.
As the liquid flows down the spiral the heavier particles (shale) stay close to the central column and the lighter particles (coal) are thrown to the outside edge.
At the bottom of the spiral there is an adjustable paddle which separates the flow into two channels: for lighter and heavier particles.
