Task of the present invention is implemented as follows, a kind of horizontal cone rotor impact crusher, it comprises and is fixed with bar on the rotor block, rotor block, belt pulley and main shaft adopt key connecting respectively, main shaft is supported by two fixing on frame bearing blocks, cylindrical shell is a split type structure, it is formed by connecting by bolt by first cylindrical shell and second cylindrical shell, be fixed on the frame, cylinder inboard wall is fixed with the polylith counterpunch board, the left side upper fixed of first cylindrical shell has material bin, and second below, cylindrical shell right side is fixed with hopper; On main shaft, be fixed with the different cone rotor body of a plurality of diameter, the multi-stage rotor that rotor block and bar constitute is cone rotor, rotors at different levels are little according to the left side, the big order in the right is arranged from small to large and is fixed on the main shaft, be fixed with several bars on the described rotor circumference, the outer rim of each bar all is included on the cone surface, and promptly the profile of rotor is tapered.
Described first cylindrical shell and second cylindrical shell are the frustoconical cylindrical shell half, respectively there is a semicircle orifice at the center of the faying face at its both two ends, the inner chamber of the whole cylindrical shell of being made up of first cylindrical shell and second cylindrical shell is frustoconical, and the feeding end diameter is less than discharge end, and main shaft is equipped with at its center.
Described counterpunch board is an arc plate left small and right large, is uniform-distribution with many helical tooths on its inwall, when rotor when rotating counterclockwise, the rotation direction of its helical tooth is left-handed.
The quantity of the rotor block of installing on the described main shaft can be one or more, forms horizontal single-stage cone rotor impact crusher, horizontal twin-stage cone rotor impact crusher or horizontal multi-stage cone rotor impact crusher.
The present invention has following advantage compared with the prior art: because this disintegrating machine is equipped with a plurality of cone rotors that vary in size on same main shaft, the linear velocity of rotor little by little evenly increases from feeding end to discharge end, meet the requirement of contrast power consumption in the carse, medium and small shattering process of material, so the crushing efficiency height, the ratio of reduction is big; The circumference of rotor surrounds counterpunch board, all participate in fragmentation at the epitrochanterian whole bars of synchronization, radial load suffered on the main shaft is less, it is horizontally disposed to add the main shaft employing, and material enters from cylindrical shell one end, discharges from the other end, therefore device height is little, machine gravity is low, and good stability is simple in structure; Cylindrical shell adopts split type structure, helps overhaul of the equipments; Disintegrating machine work interior air-flow on opportunity forms circulation along rotor circumference, and dust is difficult for escaping, and helps environmental protection.This machine be applicable to industries such as building materials, mining industry, coal and chemical industry in, operation in small, broken bits.
