The NZX series pressurized feed two-product heavy medium cyclone is a high-efficiency coal preparation equipment. It adopts a column-cone structure and uses the principle of centrifugal separation to separate raw coal into clean coal and gangue according to density. This equipment has high sorting accuracy (average possible deviation ≤ 0.03), low sorting limit (up to 0.044mm), built-in corundum wear-resistant lining, and long service life. It can be widely used in the sorting of high-sulfur coal and difficult-to-separate coal. It has the advantages of large processing capacity, low energy consumption, and easy operation.
