Our VSI sand making machine is a newly researched equipment.It owns many superior characteristics:

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, increase 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 make it possible that center feeding and ring feeding comes together, in order to meet requriement of different stones. In addition, this equipment can not only crush stone, but also iron.

7. Shape of material-throughing device is better designed, which improve the utilization ratio.
