WIRE ROPE CONVEYOR-SPREADER FOR ITEM-BY-ITEM DELIVERY OF STONE MATERIAL TO SEPARATION ZONE Russian patent published in 2003 - IPC

FIELD: mining industry. SUBSTANCE: invention relates to device for transportation and item-by-item delivery of lump material at separation of mineralized rock mass into metalliferous and nonmetalliferous parts. Said conveyor-spreader of metalliferous lumps to checking zone has feeder and group of at least two conveyors with endless load carriers installed in tandem in direction of discharge chute. Load carrier of first conveyor is made in form of system of endless wire ropes stretched between rollers and pulleys. Rollers at side of feeder are located on axle at distance from each other less than maximum linear size of lump of fraction under checking. Pulleys are installed on shaft at distance from each other less than distance between corresponding rollers and forming discharge chute in vertical plane. Diameter of outer pulleys is greater than that of inner pulleys. Outer pulleys are installed to provide moving to, lifting in direction of movement to discharge chute and increasing speed of outer wire ropes relative to inner wire ropes. Invention enlarges technological capabilities of conveyor owing to organization of flow of separated lumps for analyzing by X-ray, optical and acoustic testers. Wire ropes of conveyor can be used as screen members. EFFECT: enlarged operating capabilities. 3 cl, 5 dwg
