Overview Introduction of Sand Making Machine:

VSI vertical shaft impact crusher is a newly researched equipment with international advanced level. Advanced 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.

VSI vertical shaft impact crusher is a general term for the mechanical equipment used for producing artificial sand. Sand maker can crush and screen natural stone materials and gain sand different granularity that can be used in daily life, so that it can also be called sand crusher.

Working Principle of Sand Making Machine:
1.Center Feeding:
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 60-75 m/s. When hitting impact plate, it is crushed. Final products are discharged 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 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 60-75 m/s, hit the materials coming down from outside of material-dividing plate. In this way, material is crushed.


Technical Features of Sand Making Machine:
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.
