The crushed river pebbles are then screened by the vibrating screen, and then the river pebbles that meet the feed requirements of the impact crusher will be sent to the impact crusher for fine crushing, and then enters the sand making machine for sand making treatment. After the sand is made, it is screened again by the vibrating screen.
