the stone is blasted down from the mountain,self loader truck feed the stone less than 750mm into the vibrating feeder,vibrating feeder to evenly feed the stone into jaw crusher,and the rock is crushed by the jaw crusher in the first stage. The stone from the jaw crusher is about ≤250mm.Then the material is sent to the european impact crusher through the vibrating feeder for the secondary crushing.and the material larger than 40mm is returned to the sand making machine by circular vibrating screen, and the stone below 40mm is sent to the sand making machine after the material is returned to crushing through the circular vibrating screen. Through the circular vibrating screen to classify and screen the material, the material larger than the finished product is returned to the sand making machine to be broken again, and the finished product is transported from the belt conveyor to the finished product area.
