ABSTRACT:
A method utilizing a simple mechanism to circumvent the effect of the magnetic conveyor head (12) of a magnetic separator (11), whereby ferrous material such as steel cans can be diverted from the stationary reject chute (13) to go instead to the place where nonferrous materials go. The mechanism, called a movable chute (14), is actually a movable extention of the stationary reject chute (13) and pivots up or down on a hinge device (15) that connects it to the stationary reject chute (13). It can be secured in the up position by a latching device (16). It can be maintained at a constant angle in the down position by a stopping device (17). Edges (18) to the movable chute are provided to prevent material from falling off the sides. These edges are mounted either on the movable chute or on the sides of the magnetic separator. In the latter case they are called stationary guides (19). When the movable chute (14) is in the up position it forms a straight extension to the stationary reject chute (13). When it is in the down position it creates a downward chute that directs ferrous material away from the stationary reject chute (13) and into the chamber where ordinarily only nonferrous material would go.
