Figure 3 illustrates a typical cleaning plant in which dense medium cyclones are used to process raw coal from a top size of 50 mm down to 1.0 mm. To be cost-effective, it is critical that the operating parameters in a dense medium cyclone circuit such as the one shown in Figure 3 be closely monitored and controlled.

The dense medium cyclone is mounted at a 15° angle. The lighter particles (coal) come out the upper end and the heavier particles (shale) the lower. Cyclones can be used alone or in a system with dense medium drums. Larger plants may include banks of cyclones operating together. Cyclone-only plants are suitable for the cleaning of small coals ...
