VSI Sand Making Machine is a newly researched equipment, with international advanced level. Technology and modern processing equipment make it a leading role in this industry. Usage: VSI Sand Making Machine is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material. Working Principle: (1) Center Feeding: Raw material falls down into feed hopper, then enter into impellor through central entrance hole. It is accelarated in high-speed impellor, then is thrown out at speed of 60-75m/s. When it hits impact plate, it is crushed. Final products come downwards though outlet. (2) Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two divisions by material-deviding plate. One enters into impellor through the center of material-deviding plate. The other falls down from outside of material-deviding plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-deviding plate. In this way, material is crushed.
