A performance model for coal-washing dense medium cyclones

Fine Coal Washing. Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. 8.6.5 Cyclones. The cyclones used for beneficiation of fine coal are of two types – water-only cyclones and heavy-medium (HM) cyclones. The former type of cyclones is designed such that the cone angle is made relatively longer and no heavy ...

A CYCLONE fOR a REASON – Dense Medium Cyclone Efficiency ...

Beneficiation of fine coal, nominally below 0.5 mm, with dense-medium cyclones was implemented as long ago as 1957 and cyclones are still being used to process fine coal today but the history shows that the application of cyclones in fine coal processing has not been nearly as successful as in the processing of coarser coal.

Fine coal processing with dense medium cyclones

Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and stackable form.

Cyclone - an overview | ScienceDirect Topics

Feb 27, 2007· The two spirals specifically developed for treating fine coal showed better cleaning efficiencies than the water washing cyclone on the +75 µm size fraction in the feed (essentially 1 mm top size). Their single start capacity was about half that of the water washing cyclone for the same clean coal ash content.

Cyclone - an overview | ScienceDirect Topics

Cyclones can be used alone or in a system with dense medium drums. Larger plants may include banks of cyclones operating together. Cyclone-only plants are suitable for the cleaning of small coals of less than 40 mm. Operation. In cyclones, the small particles are separated by centrifugal and vortex action (the cyclone itself does not move).
