With the vigorous construction of infrastructure nationwide, the demands for sand and stone aggregate increase. Natural sand is no longer able to satisfy the market demands, so that the demands for artificial sand are higher and higher. Next the technicians from SBM will fully specify the technical process of sand making machine.The sand making production line is mainly composed of vibrating feeder, jaw crusher, vertical shaft impact crusher, vibrating screen, sand washer, belt conveyor and central electricity control. The designed output is generally 50-500 t/h. Through many years of research and development, SBM combines vertical shaft impact crusher with international advanced level with other series of products of our company and designs a whole set of sand making production line, which takes a lead in the sand making industry.

The technical process of sand making production line: stone materials are evenly sent by vibrating feeder to jaw crusher for primary crushing. The coarsely crushed stone materials are sent to fine jaw crusher for further crushing. The crushed materials are sent by belt conveyor to vibrating screen for screening. The stone materials that satisfy the feeding granularity of sand maker will be sent to sand maker for making sand, and the rest that do not satisfy the feeding granularity requirement of sand maker will be returned to fine jaw crusher to be crushed again. The materials discharged from sand maker will be returned by vibrating screen for re-screening, and the sand that satisfy the requirement will be sent to sand washer for washing and the washed final products will be sent by belt conveyor to become final products. This production line can form two-stage closed-circuit cycle, and according to the customers needs, different configuration methods can be used.

Our sand making production line has the features of high automatic degree, low running cost, high crushing efficiency, energy conservancy, high output, little pollution, simple and convenient maintenance and the produced artificial sand conforms to the national building sand standard, even granularity, good particle shape and reasonable grading. This sand making production line has been put into use in many production sites and is proved to be the optimal choice for manufacturing artificial sand.
