Introduction
VSI vertical shaft impact crusher, or called sand maker, is a newly researched equipment, with international advanced level. Technology and modern processing equipment make it a leading role in this industry. VSI vertical shaft impact crusher is designed for highway, railway, high-rise construction, municipal, hydroelectric dam construction, concrete mixing stations to provide high-quality sand and gravel aggregate, it is artificial sand and stone shaping field preferred device.

Working Principle
1.Center Feeding of sand maker:
Raw material falls down into feed hopper, then enters impeller through central entrance hole. It is accelerated in high-speed impeller, then is thrown out at speed of ****5m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet.
2. Ring Feeding of sand maker:
Raw material falls down into feed hopper, then through ring, it is divided into two parts by material-dividing plate. One enters into impeller through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impeller at speed of ****5m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.

Features of sand maker
1.Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
2.Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity.
3.Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
4.Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
5.Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.
6.Special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. In addition, this equipment can not only crush stone, but also iron.
7.Shape of material-through device is better designed, which improve the utilization ratio.

Application of of sand maker
VSI vertical shaft impact crusher is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material.
