Coal washing plant equipment, coal washing jigs, coal washing machine Coal washing plants for the crushing, sizing, washing and drying of coal to enable it to be used in power uses a natural medium (water and the raw material) and the other uses a dense medium (with magnetite added).
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 #181;m with high separation efficiency, depending on liberation characteristics of the value minerals.

new densemedium cyclone plant at Tertre in Belgium to process 10 x 0 mm raw coal. The plant was unique in that the feed to the plant was not deslimed before processing. The raw coal was mixed with magnetite and gravityfed to two 500 mm diameter (D) cyclones at a feed pressure of 9D.

Dense medium cyclones are used for very accurate separation of particles of different density Particles smaller than 05mm are removed from the mixture before it enters the cyclone Magnetite is added to the waterparticle mixture to allow precise control of density The dense medium cyclone is mounted at aWe are a professional
Sep 01, 1991#0183;#32;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 + coal. The reasons for this are: * is the smallest particle size which can be easily rinsed on screens without excessive loss of magnetite and without blinding the screens.
Both Liquidsolid fluidized bed separator (LSFBS) and Dense medium cyclone (DMC) are used for cleaning coal of 1+ mm size. However, a comparison of LSFBS
attributed to the small amount of ''bright'' coal they contain. Asameans ofcleaning finecoal,wateronly cyclones appear attractive for two reasons: they offer likely capitalcost advantages, and they can easily be integrated inexisting densemedium washing plants.
The first sample received was 40 pounds of Grade E (9697 % 325 mesh, 90 % 30y, 36 % 5y) and the second was 100 pounds of the same material. This grade of magnetite is required for washing coal re duced to 100 mesh and is the grade expected to be used at Homer City.

cyclone supported by all the additional equipment needed to feed the cyclone and recover magnetite. The cyclone was fed at feed pressures ranging typically between 80 and 150 kPa (40 to 70D). The plant was employed to test the beneficiation of fine coal from several collieries in the country and proved that the production of low ash coal from
A further test was done where a known amount of coarse magnetite was added to the cyclone rigs sump, and fine magnetite was added incrementally. The differential indicated that stability was obtained when 43 % of the total media was coarse. With no magnetic field exerted onto the cyclone, this differential was found to be,

The objective was to produce a highquality (lowash, lowsulfur) coal, while reducing the amount of nonmagnetic material that would need to b e removed by magnetic separation. Three densemedium cyclone tests were performed using different underflow diameters to produce feed material for the flotation separations.
