Abstract
A material separator system and method for magnetically separating components of feedstock by directing the feedstock onto a thin rotating shell enclosing one or more rotating magnetic rolls capable of riding upon the interior of the shell. In one embodiment, a cam-and-bearing arrangement is used to permit the magnetic roll and shell each to rotate on its own independent axis. This provides the ability to adjust clearance, the line of contact, and the degree of contact between the magnetic roll and the shell. In another embodiment, a different arrangement provides the same capabilities. The system can be configured to drive a magnetic roll, which then drives the shell, or it can be configured to drive the shell, which then drives the magnetic roll. The system can also be configured as a retreater for retreating feedstock.
