The flow of stone production line is roughly as follows: (silo)-feeder-jaw crusher-impact crusher-vibrating screen (finished product). Firstly, the stone is evenly sent to the coarse crusher by the feeder for preliminary crushing, and then the coarse material produced is transported to the impact crusher by the belt conveyor for further crushing. The finely divided stones enter the vibrating screen to screen out stones with different specifications, and the stones that do not meet the granularity requirements return to the impact crusher for crushing again.
