The tie bar supporting a feed tray (moving mass) is attached to the reaction mass using one leaf spring and one elastomeric spring. The elastomeric spring comprises first and second elastomeric pads which sandwich a portion of the tie bar to which the feed tray is attached. The elastomeric spring operates in shear with the spring rate of the elastomeric spring being adjusted by increasing/decreasing the compressive force exerted by the first and second elastomeric pads on the tie bar. The adjustable vibratory feeder has demonstrated greatly enhanced stability over other existing systems.

A tracking system employs a strip of readily magnetizable material adhered to at least one edge of a conveyor belt used with a magnetic roll separator. The magnetic field produced by the head roller of the conveyor belt produces a continuous centering force which acts on the easily magnetized material providing proper tracking for the conveyor belt. The readily magnetizable material can be attached directly to either surface of the belt, have an edge portion of the belt wrapped around it or, in the form of a woven wire mesh, have the belt integrated into it by vulcanization. The strip of material may be continuous or intermittent.
