After gyratory crusher and cone crusher crush the limestone, VUS450 Aggregate Optimization System can process sand and aggregate continuously. On the one hand, it can classify the limestone containing a large amount of stone powder and remove the dust, then the high quality sand can be got. On the other hand, this machine can crush and squash the materials and then the aggregate with good shape can be obtained. Therefore, we can get finished products with many kinds of grade and the stone powder that can be recycled. The utilization rate of mine is almost 100%.
