Drain and rinse screens are located downstream of the DMS drum in coal beneficiation. Finer coal particles are fed from the sizing screen to a desliming screen to remove ultra-fine coal particles. Ultra-fines are fed through a classification cyclone, flotation, spiral separators, screens and centrifuges or filter presses.

The cyclones used for beneficiation of fine coal are of two types – water-only cyclones and heavy-medium (HM) cyclones. The former type of cyclones is designed such that the cone angle is made relatively longer and no heavy medium is required for separation. The water-only cyclones are an already established method and they are used in ...
