Four-rotor vertical shaft impact crusher

Abstract

The invention discloses a four-rotor vertical shaft impact crusher. The four-rotor vertical shaft impact crusher comprises a machine frame, motor groups, transmission groups, a four-rotor crushing cavity, four feeding hoppers and four rotor groups, wherein crushing cavity walls are fixedly mounted at the positions in the middle of the upper surface of the machine frame, and forms the four-rotor crushing cavity with the upper surface of the machine frame; each of the four rotor groups is mounted in the four-rotor crushing cavity, and the four rotor groups are separately mounted at the middle positions in the machine frame; each of the four rotor groups is in transmission connection with the corresponding rotor group; two motor groups are mounted on the left side of the machine frame, and the other two motor groups are mounted on the right side of the machine frame; each of the motor groups is in transmission connection with the corresponding transmission group; the four feeding hoppers are also fixedly mounted at the upper end of the corresponding crushing cavity wall. The four-rotor vertical shaft impact crusher disclosed by the invention is novel and unique in structure and good in operating stability; a material hedging area is enlarged, and the crushing strength and the crushing rate of materials are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of crushers, in particular to a four-rotor vertical shaft impact crusher. 【Background technique】 [0002] At present, vertical shaft impact crushers are all crushers with one rotor group, that is, the rotor crushing mechanism in the vertical shaft impact crusher mainly adopts a single rotor group, single cavity type 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 is thrown out. The maximum r...
