On described a kind of arc tooth plate, with the cracker teeth roller of rib sword tooth and reinforcement, it is characterized in that: in described a plurality of roll shafts, form between two one group.

On described arc tooth plate with the cracker teeth roller of rib sword tooth and reinforcement, it is characterized in that: on the exterior arc surface of described a plurality of roll shafts, along the circumferential direction the both sides at each axial keyway are respectively equipped with screw hole, described a plurality of installing holes are corresponding one by one with described screw hole respectively, there is screw corresponding through described a plurality of installing holes and be screwed in screw hole corresponding thereto respectively, described a plurality of arc tooth plates are fixedly mounted on respectively on the exterior arc surface of a plurality of roll shafts.

During use, power-on, slows down and transmission device makes two roll shafts do to rotate in opposite directions.From top, add ore, canine tooth and little tooth carry out splitting and shearing-crushing to ore equably, and lump ore is broken into qualified particle.

The utility model has changed the structure of discaling roll in prior art, and its object is: 1, adjacent ribs sword tooth, between roller tooth, along the circumferential direction increased reinforcement, and greatly improved the intensity of roller tooth, also improved the crushing efficiency of roller tooth simultaneously; A plurality of arc laminating roll surfaces are installed, and have protected roll surface, have omitted the protection on roll body surface; 2, the rib sword of projection has significantly reduced the contact area of roller tooth and ore, has reduced the abrasion of roller tooth; 3, on a plurality of axial keyways that are along the circumferential direction provided with on roll shaft exterior arc surface and the inner arc surface of arc tooth plate, be respectively equipped with and a plurality of axial keyways positioning spline one to one, between corresponding axial keyway and positioning spline, be separately installed with flat key, arc tooth plate is positioned on roll shaft exterior arc surface, simplified processing technology, reduced production cost, facilitated simultaneously and installed and maintenance, time saving and energy saving.

The utility model has the advantages that:

The utility model is simple in structure, improved crushing efficiency, can make simultaneously product seed evenly, cross that crushing is few, energy consumption is low, production capacity is high, and the utility model installation and operation is steady, noise is little, dust is few, consumption noble metal is few, and cost is low, adjusts easy to maintenance, particularly thoroughly solve broken teeth and high abrasion problem, greatly reduced the operation and maintenance cost of equipment; Arc tooth plate is connected and is positioned on roll shaft exterior arc surface by key, has simplified processing technology, installation, adjustment, easy to maintenance.
