Structure type impeller breaker

Abstract

The invention relates to a structure type impeller breaker, comprising a rotor; the structure type impeller breaker is characterized in that: the rotor comprises a bottom plate (1), a ring-shaped top plate (2), a material dividing cone (3) and a plurality of connection plates (4); the material dividing cone (3) is fixed on the bottom plate (1) by a fastening piece, the connection plates (4) are arranged between the bottom plate (1) and the ring-shaped top plate (2), and a material blowing opening (5) is formed between the adjacent connection plates (4); a discharging outlet protecting ring (6) is arranged at the center of the ring-shaped top plate (2), an upper protecting ring (7) is welded at the outer ring of the ring-shaped top plate (2), a lower protecting ring (8) is welded at the outer ring of the bottom plate (1), and a wear resistant material layer is arranged on the outer surface of the connection plate (4); a replaceable injection orifice lining plate (9) is arranged at the same sides of all material blowing openings (5), and an upper padding plate (13) and a lower padding plate (14) are respectively welded on the upper and lower surfaces of the material blowing opening (5). The structure type impeller breaker radically solves the difficult problem that a rotor wear-out part is hard to be used repeatedly after being worn out, a great amount of raw material can be saved and the cost is reduced.

Description

technical field [0001] The invention relates to a building material machine, in particular to a rotor crusher for crushing cement clinker or ore, in particular to a structural rotor crusher with replaceable wearing parts in the rotor. Background technique [0002] As we all know, rotor crushers are widely used in cement kilns, stone processing and other building material production enterprises to crush cement clinker and process stones. The crusher relies on high-speed rotation to throw the raw materials entering the rotor from the nozzle at a linear speed of not less than 60 m / s and hits the wall of the crusher barrel to crush the raw materials to achieve the purpose of crushing. The raw materials are crushed while rotating at high speed. The nozzle of the rotor is worn, and at the same time, the bouncing fragments repeatedly hit the surface of the rotor that can be hit. Therefore, the rotor is required to have high strength and rigidity and good wear resistance to adapt to...
