A magnetic drum separator for the separation of ferrous and non-ferrous materials from a material stream that comprises an outer shell that is rotatable by a drive mechanism. The outer shell has a tubular length, a circular cross-section, a traction plate is joined to the outer shell, the traction plate has a traction element. In another embodiment the outer shell has a tubular length, a circular cross-section, and a integral traction element. The traction elements could be a series of negative indentations, raised bumps, perforations, serrated teeth, protruding ridges, segmented protruding ridges, minor cleats, or segmented minor cleats.

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.
