Different from natural sand, the production of machine-made sand has strong controllability. By adjusting the size of the inlet and outlet of the sand making machine, it is possible to process finished sand materials of different particle sizes as required. The requirements for the particle size of the sand are strict. The production line of the company can introduce screening configuration, sand washing equipment, and integrate multiple screening and impurity removal and cleaning treatments to obtain clean Zhongxin high-grade sand and gravel. Compared with natural sand and machine-made sand, there is no obvious difference between the two. Regarding the physical and chemical indicators of machine-made sand such as grain type, granularity, and clarity, the production line has corresponding equipment configuration to process the sand, and the finished sand can meet your expectations The production effect.     What are the characteristics of the sand produced by the sand making machine
    1. Composition structure: The raw materials for processing and production of sand are all artificially selected, with uniform materials, pure compositions, and the same mineral and chemical compositions, which are not as complicated as natural sand.
    2. Fineness modulus: Generally, natural sand has one fineness modulus, while the fineness modulus of sand making is controlled by humans and can be adjusted according to needs through the adjustment process, which cannot be achieved by natural sand.
    3. Adhesion and compressive ability: The particle size of machine-made sand is usually curved. When concrete and other structural bonding are used, there will be stronger adhesion, the actual effect of compressive strength is stronger, and the service life will be Longer.
    4. Stone powder content: The large content of sand and stone powder is also an important feature different from river sand, but research shows that the general sand and stone powder content is less than 20%, which has no adverse effect on the setting time and strength of concrete.
