        Two production modes of sand making machine production line

        With the rapid development of construction projects and the increasing demand for sand and stone, it also promotes the rapid development of sand making machine. With the rapid development of construction projects, the application of machine-made sand is also developing. The market of machine-made sand is becoming wider and wider, and its manufacturing technology is becoming more and more mature. So what are the main production modes in the sand making machine production line? How to choose environment-friendly sand making equipment? Here is a brief introduction to you.

        Two production modes of machine-made sand
        With the progress of environmental protection and the prohibition of natural river sand mining, mechanical sand will gradually replace natural river sand. Domestic sand making equipment and production technology is relatively mature. Not only the cost is gradually reduced, but also the production efficiency and the production effect is constantly improving. At present, there are two mature sand production modes: dry sand production and wet sand production.

        1. Production line of wet sand making machine
          Wet sand making means that the sand produced by the sand making machine is cleaned by the sand washing machine. The quality of the finished product is close to river sand, the fineness modulus is between 2.8 and 3.1, the stone powder content is less than 3%, and does not contain mud powder, so it is very suitable for high strength concrete. The advantage of wet sand is that there is basically no dust in the production process. The use of fine sand recovery equipment, the particle size of the finished products is reasonable, excellent appearance, the market is relatively thin welcome sand and stone.
        2. Dry sand making machine production line
          Dry sand making means that the sand produced by the sand making machine does not need to be cleaned by the sand washing machine. After screening with screening equipment, the material that meets the requirements can be directly sent to the finished product heap through the conveyor.

        When making sand dry, the staff need to pay attention to the mud content and moisture content of the raw material. If the mud content is too large, it will affect the performance of the concrete. If the mud content is too high, it should be reduced before or during production. The advantages of dry sand are that it is not restricted by water and environment, can guarantee the supply to the maximum extent, and the investment of dry sand in the later stage is relatively small compared to wet sand.

        In fact, both sand production methods have their own advantages. When choosing, the user can make a reasonable choice according to the actual production situation.
