Introduction of sand making machine

Sand making machine is also known as vertical shaft impact crusher.  Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity. 

1. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance. 

2. 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. 

3. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally. 

4. 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. 

5. Shape of material-through device is better designed, which improve the utilization ratio. 

Advantages of sand making machine

1.It is suitable for a large scale production factory with 50-300 t/h production capacity. 

2.The production cost of finished sand is the 3/5 times of the conventional production line. 

3.Using sand making machine is energy saving, Besides, its crushing ratio is big. 

4.The shape of product is excellent and likes a cube. There are few needle flakes products in the finished sand. 

5.The products can put together tightly. And the iron pollution is very low.
