The present invention relates to a circulating sand manufacturing apparatus and a manufacturing method using the construction waste, the manufacturing apparatus is a tubular sorter case 10, the tubular particle diameter that is provided to be axially rotatable inside the sorter case 10. A water jet mechanism 60 for injecting water into the classifier 20, the blower 30 for forming a vortex into the particle size classifier 20, and the aggregate discharged through sidewalls of the particle size classifier 20. , A cyclone 40 for collecting the mortar separated from the aggregate by the particle size classifier 20, a suction device 50 for sucking the air of the cyclone 40, and the particle sizer 20 from the blower 30. Consists of a heat supply mechanism that heats the air supplied to the inside of the filter, selects the circulating sand with a particle size of less than a predetermined size, and can remove foreign substances such as mortar contained in the circulating sand dry. It will allow the digestion. |
