After the material passes through the distributor of the sand making machine

After the material is passed through the distributor of the sand making machine, it will be divided into two parts, one part will enter the high-speed rotating impeller from the middle of the distributor, and it will be rapidly accelerated in the impeller, and its acceleration can reach hundreds of times of gravity acceleration, then 60- The speed of 70 m / sec is ejected from the three uniformly distributed flow paths of the impeller. Firstly, it is crushed and broken with a part of the material falling from the periphery of the distributor, and then impacts on the material lining in the vortex cavity, rebounds by the material lining, impacts obliquely upward to the top of the vortex chamber, and changes its moving direction. The deflection moves downward, and the material emitted from the impeller flow path forms a continuous material curtain. Such a material is subjected to multiple impacts, friction and grinding and crushing in the vortex breaking chamber. The broken one 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 crushed by themselves, and are not in direct contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces the angular pollution and prolongs the wear time of the Artificial sand for construction. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.
