Four-rotor crushing mechanism

Abstract

The invention discloses a four-rotor crushing mechanism. The four-rotor crushing mechanism comprises four rotor sets, multi-spoke frames, a bracket arm support mechanism, four material partitions, four inspection doors, a crushing cavity wall, a bracket arm support member and a base platform, wherein the crushing cavity wall is vertically and fixedly installed on the base platform and forms a crushing cavity together with the base platform, the upper end of the crushing cavity is open, the bracket arm support mechanism is fixedly installed in the symcenter of the crushing cavity, the four rotor sets are all installed in the center of the crushing cavity wall and form a crushing area, the multi-spoke frames are respectively installed on the rotor sets, each multi-spoke frame is formed by a buffer charging barrel and three multi-spoke frame arms which are arranged around the periphery of the buffer charging barrel, the four inspection doors are installed on the periphery of the crushing cavity wall, and the four material partitions are further arranged on the base platform. The four-rotor crushing mechanism has the advantage of reasonable structure, and the four rotor sets form a plurality of material hedging areas, so that the crushing strength and collision rate are increased, and the crushing strength and crashing rate of materials are increased.

Description

【Technical field】 [0001] The invention relates to the technical field of crushing mechanisms, in particular to a four-rotor crushing mechanism. 【Background technique】 [0002] The rotor crushing mechanism is the mechanism for performing material crushing of the vertical shaft impact crusher. At present, the rotor crushing mechanism in the vertical shaft impact crusher mainly adopts a single-rotor, single-cavity single-rotor crushing mechanism. Its working principle is to use the high-speed rotating rotor to throw the material out, and then the high-speed thrown material collides with other materials in the crushing chamber or directly hits the inner wall lining of the crushing chamber, so that impact crushing occurs. [0003] The crushing force and crushing effect of the single-rotor crushing mechanism are closely related to the rotating speed of the rotor. The higher the rotating speed of the rotor, the greater the power and the greater the impact force when the material i...

AI Technical Summary

Problems solved by technology

[0003] The crushing force and crushing effect of the single-rotor crushing mechanism are closely related to the rotating speed of the rotor. The higher the rotating speed of the rotor, the greater the power and the greater the impact force when the material is thrown out. The maximum rotor speed of the mechanism is only 1900r / min, so it is difficult to increase the impact power of the material, so it is difficult to crush the harder material
