Cyclone washers are becoming increasingly popular in Western Europe because of their high degree of performance in the washing of small sized coals. Such washers are being particularly favoured where the raw smalls have comparatively difficult cleaning characteristics or where crushed middlings are being re-treated for increased yields of clean coal. From the point of view of washing Indian coals for coke-making, cyclone washers hold out bright possibilities, as a large part of our future reserves of coking coal require crushing to smaller sizes prior to washing for the recovery of economic yields of clean coal and their cleaning characteristics are such that no efficient treatment is possible without the application of heavy medium technique. The writer, who has been intimately connected with the studies on cyclone washers at Central Fuel Research Institute (India) for a number of Years, visited some of the cyclone installations in U.K., France, Belgium and Holland including those that have recently been established incorporating the latest design and development and collected useful data on the design, operation and performance of cyclone washers. These are briefly outlined in this paper.
