1.saving cost by 30%, 2.More Excellent Shape for hard stone, 3.low cost sand making machine - details see: https://www.machineto.com/sand-making-machine-for-sale-sand-maker-sand-making-equipment-10082255

1.Introduction for sand making machine :

VSI series Sand making machine also called vertical shaft impact crusher, is a kind sand making equipment aims to produce artifical sand,VSI Sand Making Machine is of high efficiency and high performance crusher, low in maintenance and low operating cost. Our high proficiency sand making machine is designed and manufactured to produce fine quality sand with high productivity output. The final product is of cubical shape with grounded edges, which is widely used in concrete, building, construction.

2.Working principle of sand making machine :

Materials fall into the hopper and then through the central well enter the high speed rotator which will throw out the materials with high speed. Firstly, the materials strike with the materials that are free falling down. Secondly, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then deflecting fall down. Thirdly, the falling materials with the shoot materials form a continuous materials curtain. Lastly, crushed materials be discharged from the under discharging opening

3.Features of sand making machine:

1. Advanced doublepump 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. Overvibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
