Materials: a natural gravel
    Production scale: 80-100 square of sand per hour.
    Product Requirements: coarse sand to the requirements of fineness modulus Mm-2.4-3.6, in line with national standards. Natural screening 0-5 mm (6mm) of natural sand.
    About Sand Process
    By car or forklift unloading of raw materials into the hopper, use a conveyor input the materials into a Cone Crusher station, and then into the vibriating screen, material less than 40 mm into the Impact Crusher, after the screening at a 0 -3.6 mm sand, (after washing by Sand Washer). Sand fineness of the pore size can be adjusted by the screen. Sludge sedimentation and sand is complete by the sand recovery device(recovery of 22-50 type of sand), fine-grained can be fully recycled, reduce sedimentation and pollution, improve the device yield and profit values. Make this system more for the environmental value.

    Selection of Equipment Description:
 to produce the building material with river gravel - sand,there are many process methods, through twenty years of exploration and experience of foreign company, optional Vertical Impact Crusher (Sand Making Machine), its technology has been "Stone Strike" to "strike while the iron stone" and "stone at stone," a combination, and the "stone at stone" based. And compared to "Stone Strike" technology we have 10-20% rate increased in fine sand production, which is different from other domestic manufacturers .
