China has a large population and a large base of scrap metal products. Scrap metal in the development and utilization of recycling is particularly urgent, metal shredders as waste resources in the processing equipment, is to promote China's new energy recycling economy sound and rapid development of the important support. Metal shredders treated waste metal particles with clean and environmentally friendly features, but also can reduce the pollution of the environment, because the steel directly burned scrap metal products because of these waste materials on the surface of the paint will produce a lot of pollutants in the combustion, After the metal shredder in the treatment will reduce the pollutant emissions. With the new concept of low-carbon economy in China, the new policy came into being, energy and economy to the highest values of the implementation of the big changes in the outcome, may become gradually towards ecological civilization out of a new way, the application of innovative technology in the new century Innovation mechanism to promote economic development, the corresponding large-scale metal shredders have also been rapid development, due to high energy consumption is widely used. So the metal shredders not only to achieve economic development, but also to the protection of resources, and achieved a win-win situation. Many experts and scholars suggested that you can set up waste resources in the recovery of special development funds, promote green consumption, the implementation of "guaranteed pressure" policy. Development of metal shredders can not only effectively reduce environmental pollution, but also conducive to building an environment-friendly society, but also can promote China's economy to achieve sound and rapid development, and ultimately benefit the people.
