Sand making production line includes jaw crusher, VSI sand making machine, vibrating screen, sand washing machine and belt conveyor and other equipments. VSI sand making machine is produced by Longzhen by adopting the technical advantages of the like products with stone at stone and stone at iron principle, has the features of high efficiency and low operation cost. The process of sand making production line: First, the stone crushed by coarse crusher(jaw crusher), then the coarse stone is transported to the secondary crusher by belt conveyor to be deep crushed, the end products from teh secondary crusher is transported to vibration screen, it will be sorted by two parts, one parts that size is suitable to be fed to the sand making machine will be processed by sand making machine into sand, and the other parts that the size is bigger will be processed by crusher again till the size is suitable for the feeding size. The original sand from the sand making machine also will be sorted by two parts, one parts that the size meet the requirements will be transported to sand washing machine and be processed to end sand after cleaned, the other parts that the size is not meet the requirements will be processed again by sand making machine till the size meet the requirements. Features: High efficiency, low operatioin cost, energy conservation, high productive rate, low contamination, easy maintenance, even end particles, good shape and meet the state building sand requirements.
