The application of waste metal resources can greatly increase the utilization of natural mineral resources, increase the use of land, reduce the total energy consumption, waste investment, maintain the ecological environment, and improve the benefit of rest and consumption. Especially in the world where natural mineral resources are extremely consumed and increasingly scarce, scrap metal resources are in the world economy. The more prominent the position in the strategy can be continued. At present, all countries in the world are actively and effectively recycling the waste metal resources, so as to appropriately curb the temporary consumption of mineral resources and power. Scrap iron and steel for iron and steel consumption is the only substitute for iron ore, and more restricted development and use of waste steel resources is an important way for the iron and steel industry to achieve energy saving, clean consumption, recycling economy, and alleviating the iron ore resource crisis. At present, the recycling rate of scrap steel in China is 19.9%, far below the world average of 48.3%. The trend of the national waste steel disposal industry is to take the scrap and separation and separation as the leader, and to apply the new and new technologies such as environmental protection and mechanical and electrical integration to develop a new comprehensive disposal technology for waste steel, which can form the environmental protection industry and the new economic growth point. The steel shredder plays a vital role in the recycling application of scrap steel resources, and has great prospects for application and development.
