[0002] With the continuous acceleration of engineering construction, demolition waste and decoration waste are growing at an alarming rate. The overall resource utilization rate of demolition waste and decoration waste in my country is low. At present, the traditional treatment methods of home decoration construction waste are mainly landfill and accumulation. Home decoration construction waste mainly includes demolition waste and decoration waste. The main components of demolition waste are concrete blocks, bricks and tiles, metals, plastics, etc. containing steel bars, while decoration waste is more complex than demolition waste, including a small amount of bricks and tiles, concrete blocks, gypsum boards, wood, plastics, rubber, glass products and other impurities. However, the resource utilization methods and final products of the two types of waste are basically the same. Therefore, how to coordinate the resource utilization of demolition waste and decoration waste, share the two types of waste treatment equipment such as crushing, screening, and air separation, reduce customer investment, effectively utilize land area, make full and effective use of limited land, efficiently recycle aggregates, compress and package metals and light materials for reuse, and turn waste into treasure has always been a technical problem that needs to be solved in the industry.
