Abstract

A magnetic separator system comprises a feed chute having an adjustable feed chute floor portion for controlling the release of discharge slurry from the feed chute onto a rotating magnetic drum separator. Adjusting the adjustable chute floor portion controls where discharge slurry released from the feed chute contacts the outer surface of the drum, allowing the contact point to be maintained for optimal separation simply through such adjustments. Precise control over flow of discharge slurry onto the drum notwithstanding variations in flow of discharge slurry permits the system to use an open construction, which is more compact and which reduces wear and abrasion and makes the system more accessible for repair. The field of attraction from magnets within the drum extends not only around the circumference of the drum, but also into the feed chute over the adjustable feed chute floor portion. This enables magnetic separation to take place in two phases: both while the discharge slurry is still flowing in the feed chute, and after the discharge slurry falls into contact with the drum. The drum is preferably covered by a replaceable protective lining constructed in segments that are easily installed and removed, but which overlap and interlock with one another to form a sealed protective lining.
