Filed: 1927-12-06
Abstract: 287,499. Erz-u. Kohle Flotation Ges., (Assignees of Wunsch, R.). March 22, 1927, [Convention date]. Upward-current classifiers; stationary-vessel washing-apparatus.-A method of classifying and grading the constituents of a mixture of coarse and fine granular material consists in subjecting the mixture while it is being transported under water to cross currents which separate the fine grains, the separated finer material being subjected to a second separation in a zone of hindered settling created by the pump itself. In the form shown in Fig. 1, the material is fed from a shoot 1 on to the lower end of an inclined screen 4 up which it is transported by a conveyer and discharged on to a second conveyer 5. While being transported cross-currents of water are played upon the material whereby the finer grains are separated. The finer grains, together with any coarser grains separated therewith, pass over a sill 6 into a conical compartment 7 forming the zone of hindered settling and having an exit adjustable by a wedge 8 where the coarser grains settle and are discharged on to the screen, while the finer grains pass over a weir 9 into a launder 10. As shown in Fig. 2, the material falls in a cascade over plate 4<1> - - 4<4> constituting steps below which are disposed nozzles 5<1> - - 5<4> through which air is injected, the jets passing transversely through the falling material. The coarser grains are discharged through a valve 9 and are led away by a conveyer, while the lighter grains pass over a sill 6 into a similar hindered settling chamber 7. Regulating means for the jets are provided in both forms. In the Specification as open to inspection under Sect. 91(3)(a) a modified form was described in which the lighter grains pass over a sill 9, Fig. 2 (Cancelled) on to a conveyer 10 passing under a water-jet 19 which further separates the lighter grains from any coarser grains; these coarse grains are discharged on to the conveyer 8 while the light grains fall into a tapering chamber 11 and are discharged by a pipe 13. This subject-matter does not appear in the Specification as accepted.
