Abstract

712,792. Centrifugal - separators; washing granular materials. DORR CO. June 4, 1952 [June 14, 1951], No. 14113/52. Classes 23 and 82 (2) [Also in Group XXIX] Slime is removed from a liquid suspension of coarser solids interspersed with slime in a hydro-cyclone comprising a cylindrical part 121, a conical part 122, an inlet 126, for the suspension tangential to the cylindrical part, inlets 141 ... 144 for desliming liquid tangential to the conical part, an outlet 129 for slime, and an outlet 197 for the coarser solids. The outlet 197 has an apertured rubber block 193 which may be axially compressed to control the diameter of the discharge passage through the outlet: The plant shown in Fig. 8 contains a hydro-cyclone 20 having inlets 240 for desliming liquid. Coal slurry is fed to the hydro-cyclone and water is the desliming liquid. The coarser solids from the hydro-cyclone are led to a filter 242, and the water extracted by the filter forms part of the desliming liquid. The slime from the hydro-' cyclone is separated in a hydro-cyclone 247, the clear water from which is also used as desliming liquid. Any additional water required for desliming is supplied by a pipe 252. Dimensions and performance figures are given in the Specification.
