Abstract
344,802. Separating solid materials. HOLMES, C. W. H., Deneside, Alverstone Avenue, Low Fell, and BIRTLEY CO., Ltd., Birtley, both in Durham. Aug. 28, 1929, No. 26219. [Class 117.] Relates to apparatus for separating mineral and agricultural products, such as a mixture of coal and shale, of the type in which the materials are subjected on a perforated support to the action of continuous or pulsating air pressure whereby the denser products are stratified below the lighter, and consists, in one form, Fig. 2, in the provision of a stationary inclined support 3 over which the materials are fed from a hopper 4, and a conveyer 9 moving over the support in an upward direction to discharge the denser material against the action of gravity. In a modification the conveyer may be formed of perforated plates which function as the support. Sides 7 form a trough, the lighter material, such as coal, being discharged by gravity at the lower end over a weir 14 adjustable in height by screws 13, the discharge of the denser material, such as rock, being controlled at the upper end by an adjustable gate 11. The apparatus may be applied to the process described in Specification 322,480, [Class 117, Sifting &c.]. Specification 299,936, [Class 117, Sifting &c.], also is referred to.
