Dense Medium Drum and Cyclone Plant
The Parnaby Dense Medium Drum and Cyclone Plant is a washing plant which enables customers to process a range of different feed material in the coal preparation industry.
This is the most efficient single piece of equipment for separating minerals and waste with different specific gravities. It can separate raw material which is 50% coal and 50% shale.
The dense medium drum is horizontal and revolves slowly (about 1 – 3 rpm). As the raw material enters the drum, magnetite is added via the water circuit to achieve the required density. This enables raw material direct from its source to be processed through a single Parnaby wash plant, separating out the impurities and providing an assortment of washed product grades. Separation is achieved entirely by the buoyancy of the medium; dynamic effect plays no part.
The coal floats near the surface of the medium and flows out of the end of the drum. The heavier shale or high density coal particles fall to the bottom of the drum and are moved along the scrolls to perforated lifters which collect and deliver into a waste chute.
Parnaby Cyclones can manufacture 2 product and 3 product drums.
