Process for improving the quality of separated materials in the scrap metal industry

摘要

What is presented is a process for scrap metal processing for shredding and sorting recoverable material from a material stream that comprises a ferrous fraction, a non-ferrous fraction, a waste fraction and a less ferrous fraction that includes composite materials. The process comprises first shredding the material stream with a first shredder to a size that enables downstream processing. The shredded material stream is then conveyed to at least one drum separator to remove the non-ferrous fraction from the material stream and then conveyed to a first conveyor separator to further separate the ferrous fraction from the material stream. At the completion of these steps the remaining material stream to be handled by downstream processes represents 10% to 40% of the original material stream as compared to 70% to 75% of the material stream in the prior art.

1. A process for scrap metal processing for shredding and sorting recoverable material from a material stream comprising a ferrous fraction, a non-ferrous fraction, a waste fraction and a less ferrous fraction that includes composite materials, comprising:
shredding the material stream with a first shredder to a size that enables downstream processing; conveying the material stream to at least one drum separator to remove the non-ferrous fraction from the material stream; and conveying the material stream from the at least one drum separator to a first conveyor separator to separate the ferrous fraction and the waste fraction from the material stream.
