Sandstone production line is also called Aggregate Plant. It is a special designed plant for producing sand and stone for construction. The finished products include various sizes stone and artificial sand, which is equivalent to the combination of stone crushing line and sand making line. Firstly, large stone is fed into jaw crusher evenly by vibration feeder through hopper for primary crushing , and the crushed stone is fed into crusher equipments (cone crusher or impact crusher) by belt conveyor for secondary crushing. The crushed stone is fed into the aggregate screens by belt conveyor for screening. The finished sand (undersize material) is sent by the belt conveyor to the aggregate washers for cleaning, and then clean final products will be discharged.
Larger stone (oversize material) is sent to sand making machine (vertical impact crusher) by belt conveyor for fine crushing. The finely crushed stone is fed into the fine aggregate screens for screening again. This forms a closed circuit manifold cycles. So how to design aggregate plant?
Material from primary crushing to secondary crushing to screening, different types of equipment may be used at different stages. In the design, sufficient adjustment space should be reserved so that operators can adjust on demand.
Reserving a buffered hopper to ensure uniform feeding and full feeding for cone crusher, which is beneficial to both the efficiency of cone crusher and the protection of bowl liner and mantle (Cone Crusher Common Problems).
