Abstract

The application discloses a positive electrode material grinding system based on gas compression technology and a processing method, relates to the material crushing technical field, and comprises an airflow mill, an air inlet pipe and a feeding channel which are arranged on the airflow mill, and a ring-shaped fixing frame which is detachably connected to the airflow mill through a fixing piece. A rotatable support is arranged on the inner side of the ring-shaped fixing frame, a ring body is fixedly connected to the support, the ring body is rotationally connected with the ring-shaped fixing frame, and a nozzle assembly capable of changing the air injection amount of the air inlet pipe is arranged on the ring body. The motor is used to drive the rotation of the ring body, the transmission part is sealed, the sealing plate is used to shield the rotating part of the ring body from above, the influence of the falling material on the ring body is avoided, the normal switching of the nozzle in the dust environment is avoided, the particle size of the processed product is changed by adjusting the nozzle, the working efficiency is improved, and the like.
