Working principle of GPR vertical shaft impact crusher

GPR vertical shaft impact crusher (also known as sand making machine) has two feeding modes, full center feeding: the material falls into the feeding hopper and enters the high-speed rotating rotor through the central feeding hole. It is fully accelerated and thrown through the launch port. It first collides with a part of the material that falls freely after rebounding, and then impacts together with the vortex material lining (or impact block) in the surrounding vortex chamber, and is first rebounded to the crushing chamber. At the top of the impeller, the rear deflection moves downward, colliding with the material emitted from the impeller flow channel to form a continuous material curtain, and is finally discharged through the lower discharge port.Center feeding is accompanied by annular waterfall feeding: the material falls into the feeding hopper, then falls through the annular hole, and is divided into two shares by the bulk material plate.One stream enters the high-speed rotating impeller through the material distribution plate, and the other stream falls from the surroundings of the material distribution plate. The material entering the impeller is rapidly accelerated in the impeller and then thrown out at high speed. First, it collides with the other part of the free falling body around the bulk material plate. The material is impacted and broken, and then hits the vortex material lining (or impact block) in the surrounding vortex cavity together. It is first rebounded to the top of the crushing cavity, and then deflected downward to collide with the material emitted from the impeller channel. The impact forms a continuous material curtain, which is finally discharged through the lower discharge port.
