In the working process of sand production line, large stones are evenly fed into jaw crusher by vibrating feeder in silo for coarse crushing. The crushed stones are fed into cone crusher (or counterattack crusher)shijiazhuang.71ix.cnwww.juanzhiji.com.cnwww.dianzugui.com.cnwww.shoutao.org.cn

The crushed stones are fed into vibrating screen by belt conveyor for screening, and the finished sand is fed to sand washer for cleaning. After washing, it is sent to the finished material stack by belt conveyor; large granular stone (screen top) is sent by belt conveyor to vertical impact crusher (sand making machine) for fine crushing, and fine crushed stone is sent to vibration screen again by belt conveyor for screening, thus forming closed circuit multiple cycles.
