Abstract
852,307. Screening apparatus. ALLISCHALMERS MANUFACTURING CO. Feb. 5, 1959 [Feb. 5, 1958], No. 4158/59. Class 117 A screen 30 comprises a frame 32, 33, 38 carrying spaced transverse rods 31 loosely supported at their ends in slots 37 in racks 35. detachably-secured to the frame side members 32. to permit rotary and sliding movement of the rods. A central rack 41 extending between the frame end members 33 has similar slots therealong to receive the rods, and detachable rod retaining plates 40, 44 are located at the tops of the slots. The screen is supported by cantilever springs 49 attached at 50 to fixed side beams 48, and the frame is vibrated by a motor 51. The latter drives a shaft 59 within a tubular housing 67 and mounted in bearings 60 on the beams 48, and eccentric portions of the shaft engage bearings mounted on the side members 32 of the screen frame. Counterweight assemblies within housings 75 rotate with the shaft. The racks 35 and 41 may be replaced by others having different slot spacing. Material, e.g. iron ore, is fed from a hopper 13, conveyer 17 and screen 21 to the screen 30, and the smaller material passes from hopper 25 to conveyer 26 and the larger material flows to a conveyer 79. A number of such screens may be arranged in series with the rod spacing of each screen less than that of the preceding one.
