washing plants where small coal is washed. (There may still be one DWP plant in operation somewhere) The top size of coal being washed is normally between lOmm and-20mrn, while the bottom size is usually O.5mm. The most popular dense medium cyclones in older plants are the 500mm, 600rnrn and 660mm diameter units.

One combined cyclone and dense medium drum plant can process up to 500 tph of coal up to 200mm particle size. Dense medium cyclone- only plants can be supplied for washing small coal below 50mm particle size.
