The utility model discloses a cold quick -witted bulk cargo collecting system of ring, this system is including the cold machine of ring, ring air -cooler, weighted valve, annular air trough conveyor, chute fan, apron feeder, belt feeder. The material gets into the cold machine of ring and cools off from one last process, and along with the slow removal of the cold board car of ring, the circulatory motion is done at the cold built -in of ring to the material, and during the discharge opening department that moves drew off apron feeder, the bulk cargo drew off among the apron feeder through the defeated material chute of bulk cargo ash bucket, weighted valve, annular air of the cold machine of ring. The utility model discloses can overcome the problem that current process?systems leaks out, leaks material, raise dust to the manual work can be reduced, the manufacturing cost of enterprise is reduced.
