A CYCLONE fOR a REASON Dense Medium Cyclone Efficiency

Oct 22, 2016· Abstract. Cyclones have been in mineral processing since the first patent in 1912 and amongst the many uses of the configuration of the cyclones is the DENSE MEDIUM CYCLONE, used for separation of particles of different densities; separation enhanced by the use of either magnetite or ferrosilicon as an essential element of the process to create the desired effect.

Dense medium cyclones for coal washing. Free Online Library

Dense Medium Cyclones for Coal Washing The dense medium cyclone was first developed at Dutch State Mines in the 1940s and since that time it has gained tremendous popularity all over the world, particularly for treating coal in the intermediate size ranges.

DENSE MEDIUM CYCLONE

coal washeries incorporated dense medium cyclones in intermediate size coal washing circuits. Presently, 55-60% of the washed coal is produced by dense medium cyclones. Realising the role of dense medium cyclones in our washeries, author and his co-workers undertook many research projects on DM cyclones during the last two decades.
