Problems solved by technology

The existing counterattack blow bar crusher mainly includes the first counterattack device, the second counterattack device and the third counterattack device. There are still defects in the structural design, and the required crushing granularity cannot be fully achieved. It brings trouble, because some large pieces of unbroken minerals hit the safety door of the front casing with the high-speed rotor, the noise is extremely loud, there is a lot of dust, and some minerals in the vertical direction will bounce heavily on the bottom with the linear speed On the conveyor belt, the service life of the conveyor belt is greatly damaged; due to the large blanking space, the material flies randomly during blanking, and cannot completely fall on the conveyor belt, which brings difficulties to the follow-up cleaning work

Abstract

The invention discloses an impact flat hammer crusher, which comprises a body, wherein a first impact device, a second impact device and a rotor are arranged in the body; a discharge port is formed in the body below the rotor; a third impact device is arranged at one side of the discharge port; a fine charge device is arranged at the other side, opposite to the third impact device, of the discharge port and comprises a fine feed baffle, which faces a working surface of the third impact device. By virtue of the technical scheme, the fine charge device can give another circulation impact on part of uncrushed bulky minerals in addition to original crushing, thus increasing the crushing times, further refining the feed, reducing elastic force on a conveying belt matched with the crusher, and prolonging the service life of the conveying belt. Moreover, as the fine feed device is mounted at the other side, opposite to the third impact device, of the discharge port, the material falling space is reduced, and feed scattering is alleviated.

Description

technical field [0001] The invention relates to the field of crushers, in particular to a counterattack blow bar crusher. Background technique [0002] The counterattack blow bar crusher uses the belt to drive the rotor shaft to move. The material is crushed by the high-speed impact of the blow bar rotating on the rotor, and then the material bounces back from the impact surface to the blow bar area for re-crushing. This process is repeated. until the material is crushed to the desired particle size. The existing counterattack blow bar crusher mainly includes the first counterattack device, the second counterattack device and the third counterattack device. There are still defects in the structural design, and the required crushing granularity cannot be fully achieved. It brings trouble, because some large pieces of unbroken minerals hit the safety door of the front casing with the high-speed rotor, the noise is extremely loud, there is a lot of dust, and some minerals in t...
