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.

The medium density at which the separation between more dense and less dense material occurs is called the cut point density. Invariably, there often is a percentage of the feed coal distribution which gets trapped in an envelope of zero velocity inside the cyclone where .

What's more, with the trend of improving coal product quality and coal washing efficiency, many coal washing plants chose to replace jigging by HMC(heavy medium cyclone). However, although the separation effect of heavy dense medium is better than jigging, the coal washing process is relatively complex with high cost.
