Vsi impact crusher for sand making high quality simple operation

Working principle

The material enters the sand making machine from the feeding hopper, and the material is divided into two parts by the feeder, and a part is inserted into the high-speed rotating impeller from the middle of the distributor and is rapidly accelerated in the impeller, and the acceleration can reach hundreds of times of gravity acceleration. Then, it is ejected from the three uniform flow channels of the impeller at a speed of 60-70 m/s. First, it is impacted and broken with a part of the material falling from the periphery of the distributor, and then impacted together on the material lining of the vortex cavity. The material lining rebounds, impacts obliquely upward to the top of the vortex chamber, changes its direction of motion, deflects downward, and the material emitted from the impeller runner forms a continuous material curtain.

Such material is subjected to two or even multiple chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge opening. It forms a closed circuit with the circulating screening system. Generally, the material can be broken into 20 mesh or less after three cycles. During the whole crushing process, the materials are crushed and broken by themselves, and are not in direct contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces pollution and prolongs mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.
