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.

Abstract: An apparatus for separating non-ferrous metal particles from residue composed of rubber, dirt, wood, plastic, glass, an the like, as well as the non-ferrous metal particles. The residue is transported by a conveyor belt over a pair of rotating magnetic separating discs which generate a magnetic field flux upward. This magnetic field flux induces an eddy current in the non-ferrous metal particles. The eddy current is a repulsive force to the magnetic field flux, which enables the non-ferrous metal particles to be levitated above the conveyor belt and the other residue material. The rotation of the field accelerates the particles off the side of the conveyor belt, into discharge chutes which collect the separated particles for recycling. The other residue material is collected at the end of the conveyor belt.

Padded baffles are provided in the air separator for reducing the downward velocity of the second material stream, which substantially lowers breakage of glass articles.

Abstract: Separation apparatus and method for separating relatively magnetic particles from a stream of particulate material made up of relatively magnetic and relatively non-magnetic particles. A mixture of the magnetic and non-magnetic particles flows in a three-dimensional stream in a common path closely adjacent to the wall of a channel. A magnet producing a strong magnetic field force is located adjacent the wall of the chamber to produce a strong horizontal magnetic force and a vertical force which is less than that of gravity. The free fall of the particles adjacent the channel wall is interrupted in the vicinity of the magnet to cause the particles to move away from the wall. Thereafter, the magnetic particles move back towards the magnet whereas the non-magnetic particles are not drawn away from their diverted path.

A main flow of air passes upwardly through the airflow passageway from the lower inlet end and develops a highly turbulent vortex-like airflow. The airflow, in combination with the magnetic field, effects separation of the light and heavy fractions of the material.
