Electrostatic Separation of Coal and Fly Ash Components
Three methods for electrostatic cleaning of finely ground coal (80% w/w − 200 mesh) have been investigated. The methods differ mainly in the way of charging the coal particles, viz. tribo-charging in a cyclone, contact charging during fluidization, and corona charging on a drum. The cleaning processes are hampered by the small particle size and the broad particle size …
