Sand and gravel production line is a special production line equipment for producing construction sand and stone. The sand and gravel production line is defined according to the type of discharge. The finished products include stone and artificial sand, which is equivalent to the combination of the stone production line and the sand production line. In the raw material factories for road construction and construction, sand and building stone production lines are often required. The sand and stone production line equipment can meet the requirements for the simultaneous production of various sizes of building stones and artificial sand.
During the working process of the sand production line, large stones are evenly fed into the jaw crusher by the vibrating feeder through the silo for coarse crushing, and the coarsely crushed stones are sent to the cone crusher (or impact crusher) by the belt conveyor Machine) is being crushed, the crushed stone is sent to the vibrating screen by the belt conveyor for sieving, and the finished sand (under the vibrating screen) is sent to the sand washing machine by the belt conveyor for cleaning, and then sent to the finished material through the belt conveyor Heap; large-grained stone (below the vibrating screen) is sent to the vertical impact crusher (sand making machine) by the belt conveyor for fine crushing. The finely crushed stone is sent to the vibrating screen by the belt conveyor for screening.
