Great Wall - Stone Crushing Plant

• High degree of automatic operation; the entire production line requires almost no manual operation except for machine starting, stopping and routine maintenance.
• High productivity, low investment and good earning.
• Regular end product granularity, good grain shape and low powder output.
• Adapting high advanced control system to ensure security and reliable operation of the complete production line. 

High hardness material crushing: large pieces of stone would be fed into the silo by forklift, then transferred to jaw crusher evenly for primary crushing by vibrating feeder below the silo. Crushed material would be transferred to cone crusher by belt conveyor for fine crushing process, finely crushed material would be transferred to vibrating screen by belt conveyor to separate. Materials which don’t meet requirement would be returned to cone crusher for second crushing, materials which meet the requirement would be transferred to vertical shaft impact crusher for shaping, shaped stones would be transferred to vibrating screen by belt conveyor to separate. Various sizes of screened material would be transferred to different piles by belt conveyor.

Low hardness material crushing: when materials with low hardness are crushed for stone production, jaw crusher is still used for coarse crushing, and impact crusher is only used for secondary fine crushing, vertical impact crusher is not needed for shaping. The crushed materials of impact crusher are sent to the vibrating screen by the belt conveyor for screening to get various granularity stones. The large stones that do not meet the particle size requirements are returned to impact crusher by the belt conveyor for re-crushing. The stones with the particle size requirements are respectively sent to the finished material pile by belt conveyor.
