Embodiment Construction

[0024] As shown in the figure, a vertical impact crusher includes a crushing chamber shell 4, a rotor 2 set in the crushing chamber shell 4, and a feeding device 1 for feeding the rotor 2, the rotor 2 and the crushing chamber shell The space between the bodies 4 forms a crushing chamber 19, wherein, in the prior art, the shell of the crushing chamber is directly called a vortex crushing chamber. The feeding device 1 feeds materials into the crusher through the crusher feed port 16, the crusher feed port 16 is fixedly connected with the fixed protective cover 8 provided outside the crushing cavity shell 4, and the fixed protective cover 8 is fixed on the crusher frame 9 Above, the feeding device 1 is fixed in the feed port 16 of the crusher, so that the feed port 16 of the crusher and the feeding device 1 are fixed and do not rotate together with the crushing chamber shell 4, so as to ensure the stability of feeding. The material enters the rotor 2 through the feeding device 1....

Abstract

The invention relates to a crusher, in particular to a vertical impact crusher which comprises a crushing cavity shell, a rotor arranged in the crushing cavity shell and a feeding device used for feeding for the rotor. A crushing cavity is formed by the space between the rotor and the crushing cavity shell. Materials entering the rotor are thrown out from multiple distributing openings formed in the circumferential side wall of the rotor and fly to the crushing cavity shell to be subjected to impact crushing. The crushing cavity shell is rotary, and the rotating direction of the crushing cavity shell is opposite to the rotating direction of the rotor. A plurality of impact plates are arranged in the crushing cavity, rotate along with the crushing cavity shell and impact with the materials thrown out from the rotor. Plate hammers are arranged on the faces, impacting with the materials, of the impact plates, each plate hammer is composed of a wear-resisting plate and a hammer edge arranged at the end, close to the rotor, of the wear-resisting plate, and parts of the hammer edges protrude relative to the faces, impacting with the materials, of the wear-resisting plates. By means of the vertical impact crusher, the impact force and the impact speed of the materials are increased, and the material crushing effect is further improved.

Description

technical field [0001] The invention relates to a crusher, in particular to a vertical impact crusher. Background technique [0002] At present, the vertical impact crusher used has great limitations when crushing materials, mainly due to the limitation of its crushing method. The crushing chamber shell of the existing vertical impact crusher is fixed, and the material enters After the rotating rotor, the material is accelerated by the high-speed rotating rotor, and the material is thrown out along the direction of the resultant force by the thrust and centrifugal force of the rotor, and is crushed when it hits the shell of the crushing chamber. The ejection speed of the material depends on the rotation speed of the rotor. The higher the rotor speed, the higher the ejection speed of the material. However, when the rotor speed increases to a certain level, the material will be thrown out before being fully accelerated, so the impact speed of the material has a limit. The spe...
