Vertical shaft impact type crusher

Abstract

The invention provides a vertical shaft impact type crusher. The vertical shaft impact type crusher comprises a base, and a power device, a transmission device, a main shaft assembly, an impeller body, a feeding device, a material distribution device and a vortex crushing cavity which are arranged on the base, wherein the impeller body is rotationally mounted in the vortex crushing cavity and comprises an impeller shaft and a flow channel fixedly connected with the impeller shaft; the power device drives the rotation of the main shaft assembly and the rotation of the impeller shaft through the transmission device; and the feeding device and the material distribution device are mounted above the impeller body so that materials freely fall onto the flow channel of the impeller body. The vertical shaft impact type crusher provided by the technical scheme has a very good crushing effect; and damages to parts of a machine body by the materials are reduced and the service life of the parts of the machine body is prolonged.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a vertical shaft impact crusher. Background technique [0002] The vertical shaft impact crusher is a kind of crushing machine that uses high-speed moving materials to collide with each other to crush each other, and the materials collide back and forth between the crushing element on the rotor and the ring liner to crush each other, that is, through "rock hitting rock" or "rock hitting iron". The principle of breaking. In the existing vertical shaft impact crusher, materials such as stones are put into the body and fall onto the rotor, and the rotor rotates, so that the materials put into the crusher are pushed by the rotor and then undergo centrifugal motion to be separated from the body cavity around the rotor. However, the crushing effect of this crushing process is not good, and the rotor and the cavity are subjected to a large impact force, so that they are easily worn, whi...

AI Technical Summary

Problems solved by technology

In the existing vertical shaft impact crusher, materials such as stones are put into the body and fall onto the rotor, and the rotor rotates, so that the materials put into the crusher are pushed by the rotor and then undergo centrifugal motion to be separated from the body cavity around the rotor. However, the crushing effect of this crushing process is not good, and the rotor and cavity are subjected to a large impact force, so that they are easily worn, which affects the life of the body parts

For this reason, both the rotor and the cavity are made of manganese steel or other wear-resistant materials, but despite the use of this material, the wear of these parts cannot be avoided, and they must be replaced frequently, which increases the economic investment
