VSI Vertical Shaft Impact Crusher is the new ear of crushing field; it's widely applied in hydropower station construction, expressway and railway building, concrete batching plant, bridge and tunnel building. It has two functions of the VSI Sand Making Machine: crushing and shaping. Almost all of minerals can be crushed, contains the hardest minerals, such as metal and non-metal ores, cement, artificial sand, refractory material, bauxite, silicon carbide, glass material, building materials, etc.

Characteristics 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, 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 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.
