Vertical Shaft Impact crusher (VSI Sand Making Machine) uses a unique rock on rock crushing method employing a high speed rotor with crushing chamber of the equipment. Velocity is applied in Vertical Shaft Impact crushers as the resulting force, to break stone particles. While applying velocity rather than surface force the breaking force to be applied evenly on the surface of the rock. In Vertical Shaft Impactors material to be crushed hit the other similar covering materials at very high velocity, simultaneously the same crushed particles come in collision with another particles frequently. Mobile VSI crusher available
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.
