The minus 0.8 mm coal is further classified in a hydro cyclone at 0.1mm. The 0.5 x 0.1 mm coal is fed to the spiral circuit. The minus 0.1mm feeds the thickener, which forms the feedstock for the Flotation plant that was commissioned in August 2004. The 50 x 0.8mm coal is pump fed into a 900mm diameter DSM cyclone.

KREBS - Cyclones - Heavy-media Cyclones for Cleaning Coal ...

When it comes to cleaning coarse and fine coal, heavy-media vessels can be inefficient and maintenance-intensive. As a better alternative, our Heavy-media Cyclone, designed specifically to clean coal and minerals, is extremely efficient, using finely ground (-325 mesh/44 microns) magnetite and water as the "media."

Coal Cleaning - an overview | ScienceDirect Topics

All cyclone components (i.e., apexes and vortex finders) on the same bank of DMCs must be of the same size and type to avoid differences. Each cyclone in a bank should receive the same flow rate and quality of both feed coal and medium out of the proper feed distribution system. Otherwise, it can result in significant losses of clean coal yield.

Coal Washing Plant / Coal Preparation Plant

Coal Washing Plants consist of several sub-processing modules including raw coal preparation (crushing and screening station), pre- discharge rejects (rom jig, dense medium vessel/bath, rotary breaker), coal feeding and washing module (jigging or dense medium cyclones) as well as a dewatering module, coal handling module (conveyors, train/truck loading station, stacker reclaimer).

Abstract Wide‐angle hydrocyclone tests were conducted to separate fine (‐150 μm) particles based on differences in particle density. Mixtures of ferrosilicon (FeSi) and quartz or lead and soil of similar size ranges were separated in a 25.4 mm diameter hydrocyclone under various test conditions. Separations were made in dense‐medium suspensions of fine magnetite and water to improve the ...

New dense medium cyclone offers benefits in coal ...

DM cyclones are commonly used for separating coal from rock. Fine (minus 45 micron) magnetite is added to water to form a medium. Medium density is adjusted to a value between the density of coal and rock. High density rock moves through the medium to the cyclone wall and out of the apex, while light coal particles enter the overflow stream.

Dense Medium Cyclone

From the early 1960's until the mid 1980's, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines ("DSM") in the mid 1940's. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal ...
