Introduction:
VSI Sand Making Machine is used after fine and course material crushing process to give the perfect shape of final product. The output size can be controlled . Vertical Shaft Impact crusher is appropriate for materials with high abrasive property and silica content. It is easy to use due to simple operation mechanism.
Products features :
- Double-pump oil lubrication system is added to keep longer life time, more reliable operation.
- Main shaft work stable, lengthen maintenance cycle, increases productivity.
- Upper cover can move away easily, which saves costs during maintenance.
- Shape of material out of the device is perfect to be used in different projects .
- Over-vibration device is equipped. It will stop the machine when vibration surpasses a stipulated figure .
Working principle:
Materials go to the step of screening and washing to form final product size we required . Raw material falls down into feed hopper, then enters impellor through central entrance hole. Then is thrown out at speed of 60-75m/s. When hitting impact plate in this way, material is crushed.
