Crusher rotor

Abstract

The invention discloses a crusher rotor in the field of crusher mechanical equipment. The crusher rotor comprises a rotor disc, a wear-resistant disc and a material distribution disc which are coaxially and sequentially fixed; the diameters of the rotor disc, the wear-resistant disc and the material distribution disc are sequentially decreased. The crusher rotor is characterized in that the wear-resistant disc is higher than the rotor disc; the material distribution disc is higher than the wear-resistant disc; at least two trapezoidal impacting plates are evenly distributed on the rotor disc in the circumferential direction; at least two trapezoidal material guide plates are evenly distributed on the wear-resistant disc in the circumferential direction; the material guide plates and the impacting plates are staggered. After materials are accelerated twice, the materials are discharged from a discharging outlet, the speed of the material is large and the dispersion degree of the material is small during discharging, the materials impact on cutting plates of a crusher, and the granularity of the crushed materials is even. The abrasion to the rotor disc, the wear-resistant disc and the material distribution disc by the materials is reduced; the impacting plates and the material guide plates are trapezoidal; the materials slide on the slopes of the impacting plates and the material guide plates, applied force is reduced, and abrasion is reduced.

Description

technical field [0001] The invention relates to the field of crushing mechanical equipment, in particular to a crusher rotor. Background technique [0002] With the reduction of natural sand and the increasing amount of sand used in engineering, the market demand for sand making equipment, especially crushers, continues to increase. The types of crushers currently on the market are mainly jaw crushers, cone crushers, hammer crushers Crusher, vertical shaft impact crusher and vertical shaft impact crusher, among which vertical shaft impact crusher is also called sand making machine, which is widely used for medium crushing of various hard and brittle materials such as rocks, cement clinker, and quartz stone. , crushed. [0003] The rotor is the accelerator of the material, so it is an important structure of the vertical shaft crusher, which determines the crushing effect of the crusher. [0004] The traditional rotor structure of the vertical shaft impact crusher is mainly ...

AI Technical Summary

Problems solved by technology

The closed rotor is inlaid with hard alloy blades, and the rotor body is surfacing with wear-resistant electrodes. During the working process, there is a material pad to protect the wear-resistant parts, but the particle size of the broken materials is not uniform.
