APPARATUS AND METHOD FOR MANUFACTURING SHAPE BETTERMENT RECYCLED-AGGREGATE, CRUSHING WASTE-CONCRETE AND WASTE-ASPHALT

摘要

The present invention relates to an apparatus and method for producing recycled aggregates having improved granularity by crushing waste concrete and waste ascone in an environmentally friendly manner, and removing pastes and waste chemicals coated on the surface of waste concrete. The aim is to improve the form of aggregates and to produce high quality aggregates.;An apparatus for producing recycled aggregates having improved granularity by crushing waste concrete and waste ascones according to the present invention comprises: aggregate supply means for supplying aggregates (waste concrete and waste ascon); Sand ball spraying means impinging on the aggregate surface and supplying sand balls for removing sludge (paste, coating material) from the aggregate surface; Then, the aggregate and the sand ball is supplied through the aggregate supply means and the sand ball spraying means, respectively, so that the sludge is removed from the surface of the aggregate by the sand ball to treat aggregates, sand balls and sludges. It consists of a tank. The surface treatment tank 10 has a drum structure in which left and right sides and an upper portion are respectively opened and discharge holes are provided at a bottom thereof, and the aggregate and sand balls are respectively supplied through the aggregate supply means and the sand ball spraying means. And a driving means for rotating the drum in place, and the sand ball spraying means 20 includes: a classifier 21 for receiving and transporting sand balls, and temporarily storing sand balls transported by the transport screw. It is composed of an injector 23 for receiving the sand ball from the tank 22 and the storage tank and spraying the inside of the drum.
