Brief description is made in this article on the Iwaki-West coal preparation plant, Joban colliery, Fukushima Prefecture, which was completed in March 1961.<BR>After being sorted by Bradford breaker, 120/28mm run-of-mine coal goes to PIC-Drewboy dense-medium baths (a 2100 main washer and a 115t/h rewasher) using magnetite medium, while 28/0mm raw fines are washed by Baum jigs (a 240t/h main washer and a 120t/h rewasher).Slurries are treated in the circuit which consists of settling tanks, a thickener, and centrifuges.Jig washery refuse is retreated by a verticaltype Drewboy separator (28/8mm) and a densemedium cyclone (8/1mm) to recover low-grade boiler coals.<BR>Automatic control systems relating to dense-medium density and to jig operating variables are shortly mentioned.
