First, we can produce it by dry or semi-dry method. The artificial sand production is produced by the vertical shaft impact crusher. The content of stone powder is 20%-25%. After transformation, the content of stone powder is 18%-22%. Dry production reduces the water consumption of the system and reduces the moisture content of the finished sand, which solves the contradiction of low stone powder content and shortens the dewatering time of the finished sand.
The second point is to control the slurry concentration of the process. Appropriate control of the slurry concentration of the rod grinding mechanism sand, the concentration of the slurry is large, the sandstone powder is less lost. The concentration of the slurry can be reduced by controlling the slurry concentration of the sand grinding mechanism, and the flushing amount of the sand washing machine can be controlled to reduce the loss of the stone powder.
The third point is to set the sand fineness modulus of the vertical vertical axis impact crushing mechanism. The powder volume of the vertical shaft impact crusher is related to the fineness modulus, the fineness modulus is large, the stone powder content is low, the fineness modulus is small, and the stone powder content is high. The fineness modulus of the vertical shaft impact crusher is appropriately selected to control the stone powder content in the sand making process.
