Particles smaller than 0.5mm are removed from the mixture before it enters the cyclone. Magnetite is added to the water/particle mixture to allow precise control of density. The dense medium cyclone is mounted at a 15° angle. The lighter particles,Leeuwpan fine coal dense medium plant J r n a,Leeuwpan fine coal dense medium plant mixed with magnetite in the launder and enters a second stage washing cyclone. The product of the secondary cyclone is sent to a product magnetic separator and the discard of the primary cyclone is routed to the discard magnetic separator. The discard of the secondary washing stage is recycled back to the feed.

In most cases, the appropriate medium-to-coal ratio is determined by the coal preparation plant builder during the conceptual design phase of the project. Most dense medium cyclone circuits in the United States are operated with medium-to-coal ratios of 3:1 to 4:1, by volume. Coal preparationDense medium cyclones for coal washing. - Free Online,01.09.1991· Feed coal Even though the dense medium cyclones can treat coal down to 150 microns efficiently, the usual practice in coal washeries is to feed only +0.5m coal. The reasons for this are: * 0.5mm is the smallest particle size which can be easily rinsed on screens without excessive loss of magnetite and without blinding the screens. * To avoid,AMIT 145: Lesson 3 Dense Medium Separation – Mining,Dense-Medium Cyclones (DMC) Dense medium cyclones (DMC) have been found to be effective in treating particle size fractions between 3-inch and 100 mesh, however, not typical done in a single unit. The DMC application for treating 16 x 100 mesh material is limited due to significant magnetite loss resulting from inefficiencies on the drain-and-rinse screens.
