fine coal dewatering using hyperbaric centrifugation

Commissioned Report: Establishing Priorities for Coal

Apart from CMI HP36B, there is another fine coal centrifuge (Siebtechnik or Wemco H900) on the market. Both the machines are high G (500 G''s) centrifuges, and have similar dewatering performance. Product moisture is around 12 percent with approximately 50 tph capacity in dewatering minus 0.5mm fine coal.

Dewatering of Fine Coal Using Hyperbaric Centrifugation

The process, which may be referred to as hyperbaric centrifugation, is capable of producing a drier product than can be achieved using either filtration or centrifugation alone. The test data obtained from batch experiments show that the new method can reduce cake moistures to 10% or below for many fine coal product streams.
