Type: Three-stage crushing Input Size: 35-45mm
VSI sand making machine is a perfect combination of professional fine crushing technology and mechanical manufacturing. Its unique rotor structural design, wear-resistant material technology, crushing speed optimization and hydraulic design can be used for highways, high-speed railways, high-rise buildings, municipal construction, and hydropower. Dam construction and concrete mixing stations provide high-quality sand aggregates and are the preferred equipment for artificial sand and stone shaping.

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.
+ Working Principle
1. Center Feeding:
Raw material falls down into feed hopper, then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards through outlet.
2. Ring Feeding:
Raw material falls down into feed hopper, then through ring, it is divided into two parts by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.
