Henan Tongli Machine Manufacturing Co., Ltd. independently developed the “scrap crushing production line†project, which has passed the scientific and technological achievements appraisal of the Ministry of Industry and Information Technology. Experts agree that the result is that the domestic scrapped automobile body is broken and the scrap lightweight charge material is used to handle heavy environmental protection. The important technological breakthroughs and innovation in equipment have filled the domestic gap and reached the international advanced level. The company's self-developed, domestic first-hand scrapped vehicle vehicle dismantling equipment will disassemble a scrapped vehicle into palm-sized recyclable metals and nonmetals in less than six minutes. According to the assessment, the system adopts the pre-compression + roller wheel crushing technology creatively to make the whole car body broken once and reach the quality requirement of the scrap steel concentrate into the furnace, and at the same time, through the low-speed high-torque torn grade I pretreatment crushing and roller The kneading process design increases the value of the output and prolongs the service life of the hammer. The system combines magnetic separation, eddy current sorting, multi-stage air separation, screen sorting and other technologies to effectively recover iron and steel , non-ferrous metals , wires, plastics, and rubber. The comprehensive recovery rate is over 90%. In order to avoid air pollution during the disposal of scrapped automobiles, the system introduces air-cooled technology and supporting dust removal facilities in the cavity of the Class II crusher through negative pressure to achieve dry crushing and separation at room temperature. The entire system adopts video monitoring, man-machine isolation operation, and linkage control of the whole machine, and is equipped with a safety control system to ensure the safety of the system operation. The “urban minerals†that are based on waste electrical and electronic products, automobiles, electrical and mechanical equipment , wire and cable, metal and plastic packaging, and other consumer goods and industrial products, can be recycled for use in resources such as iron and steel, non-ferrous metals, precious metals, plastics, and rubber. It has taken up an increasing proportion of newly used resources. According to the analysis of He Guangyuan, former Minister of Machinery Industry and Honorary President of China Automobile Association, in 2010, over 4 million vehicles were scrapped. According to the current forecast of automobile production and sales, the annual scrapped volume of automobiles will be over 15 million. In addition, the use of scrap steel in China was 94 million tons in 2010, accounting for 15% of the crude steel production. The utilization rate of scrap steel in the western industrial advanced countries has reached 45%-50%, and it has been increasing year by year. The product form of the early “urban mineral†development equipment is mainly simple equipment such as scrapers and cable stripping machines that are commonly used in the recycling industry. For the sorting of materials, besides manual processing, it is the use of mineral processing equipment, savage incineration or direct landfill treatment. In industrialized countries, the treatment of urban waste is mostly chosen to be transferred to developing countries. The development of "urban minerals" development equipment in the world is lagging behind, and the environmental damage and waste of resources that this brings are startling. Therefore, it is urgent to innovate and break through the development of "urban minerals" technology and equipment.
