The purpose of recycling is to process and transform some things that cannot be directly used into useful things for continued use, while reducing environmental pollution.

At present, the main method of recycling construction waste is to grind the construction waste into sand powder. During the recycling process, the construction waste will be poured into the grinding equipment for crushing. However, because the construction waste itself contains some sand powder or gravel , These sand powder or gravel can be directly reused. If the construction waste is not separated from the construction waste first, and the construction waste is directly poured into the grinding equipment for grinding operation, it will undoubtedly waste the productivity of the grinding equipment. Secondly, construction waste often contains steel bars or screws and other metals. These metals are directly poured into the grinding equipment, which will cause wear and tear on the grinding equipment, resulting in a reduction in the service life of the grinding equipment and an increase in the use cost. In addition, the construction waste also contains plastic, Lightweight materials such as wood blocks and foam should also be removed when grinding.
