Abstract

456,432. Centrifugal separators. THOMAS, W. S., Cullinan Buildings, Simmonds Street, Johannesburg, South Africa. Feb. 1, 1935, No. 3363. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 10, 1935]. [Class 23] Apparatus for separating solid particles has a helical launder 3 arranged round a post 2 ; mixed material is supplied to the launder by a continuously operating mechanical feeder 6. At the upper part of the apparatus the floor of the launder is inclined upwardly and outwardly, but at the lower end the inclination diminishes until the floor becomes horizontal. The material is separated centrifugally as it slides down and the separate products are collected at the bottom. The flatter part of the launder has an outer wall 5 to retain the heavier parts of the material on the track. The material may be mixed with water; the post 2 may be hollow and have perforations 9 where the finer material is carried by the water. The helix is given an increased pitch in the region of the perforated part of the post.
