2. due to the lack of buildings, roads and other projects with sand, and the state attaches great importance to the resource management and environmental protection, river sand collection also limited measures, so, want to unilaterally extracted from river sand resources is quite impractical, as it is, the popularity of new sand making machine is no surprise.

3. my company in combination with the practical situation of domestic manufacturing of sand, through application research to upgrade continuously, has now developed the third generation of new scientific environment protection system sand machine production line. Widely used in all kinds of rocks, abrasive, fire-proof material, cement clinker, comprised, iron ore, concrete aggregate of many kinds of hard brittle materials such as medium and finely. Particularly suitable for building sand.

4. its characteristic is: the crushing granularity adjustment according to the requirement, and uniform particle size, large quantity and high hydraulic XiJingDu, sand loss less. Easy operation, large quantity.

5. equipment capacity, 30-200 tonnes per hour can be customized according to customer requirements.
