The solids/pulp ratio is about 18 per cent by weight, feeding the cyclone at an inlet pressure of 32′0″. The clean coal from the cyclone overflow reports to a sieve bend and onto a 6′ x 16′ clean coal dewatering screen for rinsing. The 3/8″x 28M discharge from the screen reports to a centrifugal dryer and is discharged as final product.
Hello everyone, i need help with the size of cyclone i can install to act as a bypass to the overloaded concentrate thickener and avoid dirt overflow. Basicaly i want to split the feed to thickener in 40% to 60% or what ever percentage of feed to go to the underflow at 65% solids and this will be r

COMPARISON OF DESIGNS FOR THE DEWATERING OF COAL, GOLD AND DIAMOND MINES IN SOUTHERN AFRICA . DR. MORTON . KLM Consulting Services . Lanseria, Gauteng, South Africa; email: kmorton . Although the fundamental premises underlying the choice of mine dewatering design are the same for all mines,
The benefit of total coal cleaning, which can only occur if the economics of dewatering and drying are advantageous, gives a benefit of increased revenues and decreased costs. Until an accepted economic method of dewatering coal is developed, then the separation techniques, which have been developed, will not be used to any great degree.
