Scrap metal is a kind of renewable resource. Recycling metal can reduce the amount of garbage, protect the environment, and produce economic benefits. Scrap metal crushing is considered a key part of the metal recycling process. Metal shredding can help reduce the size of materials, reduce space occupation and human transportation. When various metals are shredded, they’re easier to separate with an Eddy Current Separator (into ferrous and non-ferrous) and require less energy to melt down too, it is more friendly. Scrap metal shredders are useful machines for the volume reduction of waste such as reams of paper, paper materials, plastic, tires, refrigerators and the shredding of different metal scrap such as iron, aluminum, copper as well as municipal solid waste and industrial waste.
