Fine Coal Cleaning by Spiral and Water Washing Cyclone ...

2007-2-27  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.

Spiral Concentrators — IMSC Group

Coal/Mica Spiral Spiral Concentrators. Larger diameter units than the mineral-spiral series, these spirals are designed to take advantage of the particle shape differences. Take-off splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica.

Clean Coal - an overview ScienceDirect Topics

Clean coal particles, at least in the coarser size fractions, are usually separated from inferior coal or shale particles on the basis of their different relative density values. This is accomplished in a preparation plant by such equipment as the following: 1. Jigs, which separate the particles on a perforated deck in an up-and-down pulsating column of water
