Abstract

The application and the crusher technical field are specifically related to a medium-hard rock medium crushing type impact crusher and a working method. The crusher comprises a rotor, an impact plate part, a uniformizing plate part and a shell. The impact plate part adopts a hydraulic adjusting protection device, which greatly reduces the operation time and difficulty of maintenance adjustment. The uniformizing plate part adopts a rack structure, which greatly increases the uniformizing effect of the material, makes the material particle shape more round, and the uniformizing plate part also adopts a hydraulic adjusting protection integrated structure, which not only reduces the operation time and difficulty of maintenance adjustment, but also enhances the ability to break difficult foreign matters such as iron. The new split surface structure of the shell and the detachable side and end connection mode optimize the transportation and installation adaptability of the crusher, and the newly added and adjusted rib plate increases the structural strength of the shell and increases its reliability.
