Mechanized basalt is made by washing raw basalt stones with water to produce machine-made sand. In the basalt crushing production line, the aggregate with a particle size of<5 mm produced by the system after coarse and medium fine crushing has a high content of stone chips. The construction process used prevents this part of the aggregate from being discharged as finished material, and allows all the aggregate with a particle size of<5 mm after medium fine crushing to enter the vertical shaft impact crusher for shaping, in order to control the quality of the finished sand; The coarse particles (mainly 3-5 mm) with a particle size of less than 5mm in the aggregate processed by the secondary screening workshop cannot be discharged as finished materials. They are then sent to the fine crusher for further crushing to adjust the fineness modulus and stone powder content of the finished materials.
Mechanized basalt is widely used in railway and airport runway construction. The stone size is uniform, the texture is hard, and it is not easily weathered. It is a superior material for industries such as construction and decoration.
