At present, the natural river sand is not only sold at a high price, but reducing greatly, which cannot satisfy the need of sand in construction. However, the shortage of the natural sand resource will in turn bring bright future of the artificial sand, which can be a perfect substitution and will be a main sand source in the future. Consequently, the sand making line producing artificial sand has a promising future.
The advantages of machine-made sand: the raw materials are homogeneous and have simple composition, thus the sand has no mud and other impurities. Besides, it has perfect particle shape and grain size distribution. And also the overall cost of artificial sand is lower than that of natural sand.
Equipment in the sand making line usually include vibrating feeder, jaw crusher, impact crusher or cone crusher, sand making machine, vibrating screen, sand washing machine, dust collector, etc. Especially, VSI impact crusher is the ideal equipment to make construction sand. The whole set of equipment have the feature of small area coverage, high automation, large output with high quality of the sand.
