Feed to Zero in Heavy Medium Cyclones

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.
