Hydraulic VSI ：

1．Simple and reasonable structure ,smooth operation and low operation cost.
2． Two states of stone hitting stone and stone hitting iron can be changed freely .The equipment can be applied to manufacturing sand as well as crusher stones .The stone hitting stone technology not only reduces parts friction but also cuts down manufacturing cost .
3．Low energy consuming ,high yield ,high crushing production ,energy saving and environmental .
4．The equipment is capable of shaping out the products. Products are cubic shape and high bulk density .
5．During the manufacturing ,stone materials can form a protective bottom to avoid wearing the equipment ,so the equipment is durable in using .
6．A few rapidly wearing spare parts are made of wearing resistant material of special hardness, which is small in volume ,light in weight and easy to be changed.
7．Automatic air circulatory system can reduce the dust.
8．Moisture content of the material exerts little influence and maximum moisture can be 8%.
9．A lubrication oil station is adopted to lubricate the major bearing inn circulation to ensure a constant oil supply .It can realize automatic control and accident alert.
10．The upper is uplifted by hydraulic system, and the operation is simple.
