VSI Sand Making Machine

VSI sand making machine is the latest product of authoritative experts from both home and abroad, connecting with realistic working conditions of the quarry and mining industry, it is the high-efficiency sand making equipment with the world’s advanced levels in stone shaping field.

The machine adopts a combination crushing way of “rock-rock” and“rock-iron” with higher capacity and perfect product shape.VSI machine is the preferred equipment in making the sand industry. It is completely according to the standard of national construction sand.

Working principle

1. Center Feeding:

Raw material falls down into feed hopper, then enters impellor through the central entrance hole. It is accelerated in high-speed impeller, then is thrown out at speed of 60-75m/s. When hitting the impact plate, it is crushed. Final products come downwards though 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 the impeller through the center of the material-dividing plate. The other falls down from outside of the material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of the material-dividing plate. In this way, the material is crushed.

Feature：

1.Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer lifetime, more reliable operation.

2. The main shaft is equipped with imported precision rolling bearing. It makes the main shaft work stable, lengthen maintenance cycle, increases productivity.

3. The hydraulic lifting mechanism of the upper cover can move away from the cover easily, which saves manpower during maintenance.

4. The over-vibration device is equipped. There will be an 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 avoids dust entering bearing lubrication part, which makes 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 the requirement of different stones. In addition, this equipment can not only crush stone but also iron.
