dense medium cyclones for coal images

cyclone body for coal preparation manufacturers

Coal Washing Plants consist of several sub-processing modules including raw coal preparation (crushing and screening station), pre- discharge rejects (rom jig, dense medium vessel/bath, rotary breaker), coal feeding and washing module (jigging or dense medium cyclones) as well as a dewatering module, coal handling module (conveyors, train/truck loading station, stacker reclaimer).

01-09-1991· The dense medium cyclones for washing +0.5mm coal usually operate at a minimum feed pressure head of at least nine times the cyclone diameter, D. Larger cyclones treating wider size ranges may need a far higher pressure head than 9D. The usual range of feed pressure for dense medium cyclones is 0.4 to 0.8 kg/[cm.sup.2] (40-80 kPa).

From the early 1960's until the mid 1980's, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines ("DSM") in the mid 1940's. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal ...
