Abstract
Coal or other mineral slurry is dewatered by establishing a bed of the slurry and injecting a gas stream such as air into the bed to establish turbulent flow to strip moisture. This slurry may use particles in the range 0.5 mm to 30 mm with air injected at about 10 m/sec, and suitable novel apparatus includes a centrifuge or a vibratory conveyor with a closed tunnel and transverse air flow for stripping moisture.
