Vibratory Conveyors - renold.com

Vibratory Belt Conveyor This Vibratory Belt Conveyor will consist of a standard style belt conveyor with an integral vibratory deck. The belt will pass over the vibratory deck which will impart a vibration into the package as it is conveyed across the belt. Custom Custom units are available from test lab to full production sizes.

US6415913B2 - Excited base conveyor system - Google Patents

A base excited vibratory trough conveyor includes a trough mounted on leaf springs to a base which is excited by a linear vibratory drive. The vibratory drive produces a linear force which is oriented to be perpendicular to the springs, and the linear force is adjusted to equal the reaction force of the springs on the base during the desired stroke.
