Counter-type VSI Sand Making Machine is the main equipment of mineral processing equipment, widely used in various ores, cement, refractory materials, aluminum soil clinker, silicon carbide, glass raw materials, mechanism construction sand, stone materials and various metallurgical slag, especially for silicon carbide High-hardness, ultra-hard and abrasion-resistant materials such as silicon carbide, sintered bauxite, and beautiful sand have higher yields than other types of crushers.
The main working principle of the counter-type Sand Making Machine is that the material enters the fine crusher from the feeding hopper, and the material is divided into two parts through the feeder, and a part is transferred into the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. Acceleration can reach hundreds of times of gravity acceleration, and then ejected from the three uniform flow channels of the impeller at a speed of 60-70 m / sec. First, the part is crushed and broken by the surrounding material from the periphery of the distributor, and then impacted together. On the material lining in the vortex cavity, it is rebounded by the material lining, impacts obliquely upward to the top of the vortex cavity, changes its direction of motion, deflects downward, and the material emitted from the impeller runner forms a continuous material curtain. . Such a material is subjected to two or even multiple chances of impact, friction and grinding and crushing in the vortex breaking chamber. The finely divided 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. In the whole process of fine crushing, the materials are crushed and broken by themselves, and are not directly in contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces the angular pollution and prolongs the mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.
