Preparation Plant circuitry includes a heavy media cyclone (HMC) circuit for the 50mm x 1mm size fraction and spiral circuits for both the 1mm x 0.15m and 0.15mm x 0.05mm size fractions.
The HMC circuit consists of one each: single deck banana deslime screen, HMC sump and pump, HMC, clean coal drain and rinse screen and refuse drain and rinse screen. The clean coal screen is a double deck banana screen, modified to produce a stoker product from the HMC clean coal. The clean coal is dewatered in a horizontal vibratory centrifuge prior to exiting the plant on the clean coal collecting conveyor. The minus 1mm size fraction is further classifi ........
