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
