CONSTRUCTION WASTE SORTING SYSTEM AND METHOD FOR CONSTRUCTION WASTE RECYCLING

摘要

The present invention relates to a system and a method for sorting waste concrete powder, sand, and aggregates so that waste aggregates generated by building demolition are pulverized, sorted, and recycled. The present invention provides a construction waste sorting system including an inclined path where construction wastes are supplied from above and the inclination angle increases toward a lower end portion; a plurality of crush rollers that are provided in a middle end of an inclined surface of the inclined path and presses the construction wastes while rotating so that the construction wastes moved downward along the inclined surface are crushed; a screener that has a plurality of layers which are provided to be inclined to one side in the lower end portion of the inclined path, a perpendicularly upward side of an upper end being open for crushed construction waste insertion, perpendicularly downward sides of lower ends of the respective layers being open for screened construction waste discharge, lower surfaces of the respective layers having predetermined meshes, and the screener screening the crushed construction wastes by size; and a plurality of collection units that accommodate, by particle size, the construction wastes screened by particle size by the screener, in which each of the layers of the screener has a mesh toward a lower portion and the screener vibrates at a predetermined frequency.;COPYRIGHT KIPO 2015
