Washing Fine-size Coal in a Dense-medium Cyclone.
NTIS: PB 237 850 :6 pages
Dense-medium cyclone tests in 4- and 8-inch-diameter units have shown the ability of cyclones to make sharp separations down to 100 mesh when washing coals of a finer top size than normally fed to dense-medium cyclones. The reduced top size of the feed apparently allows the finer size particles to report to the proper product by reducing the effect of very coarse particles in the congested separation zone of the dense-medium cyclone.
