Construction waste treatment needs crushing equipment and sorting equipment. The objects of crushing operation are mainly concrete materials and stone materials. The purpose is to reduce the particle size, increase the uniformity of the shape, and facilitate the subsequent processing. When the crushed construction waste is separated by screening, air separation and magnetic separation, due to its uniform particle size and increased fluidity, the separation efficiency and quality can be greatly improved, and it is conducive to high-density landfill treatment and saves filling space. Large pieces of construction waste crushing, need to use C6x series jaw crusher, PEW series European version jaw crusher ; processing of the material particle size is generally not greater than 350mm, select CI5X series counterattack broken, HPT series hydraulic cone broken ; grinding particle size in 2-60mm particles need to select 5X series impact crushing, VSI6X vertical shaft impact crushing, VSI sand making machine

Screening is a process of separating coarse and fine materials by using a sieve to pass fine materials smaller than the sieve hole through the sieve surface and leaving coarse materials larger than the sieve hole on the sieve surface. Usually used S5X series vibrating screen, YZS vibrating screen, YKN vibrating screen
