Abstract: A vibratory apparatus includes a deck and an exciter assembly coupled to the deck. The apparatus also includes a motion sensor, a weight sensor, and a control system coupled to the exciter assembly, the motion sensor, and the weight sensor. The control system is configured to pause the rate of travel of the material across the deck for a weighing interval, to receive the signal from the weight sensor representative of a material weight on the deck during the weighing interval, to resume the rate of travel for a transporting interval, to receive a signal from the motion sensor representative of a material flow rate during the transporting interval, to determine a material mass flow rate based on the signals from the weight sensor and the motion sensor and the weighing and transporting intervals, and to vary the operation of the exciter assembly according to the material mass flow rate.

Abstract: An exciter mass assembly for vibratory processing equipment includes an exciter frame and at least one resilient member connecting the exciter frame to the vibratory processing equipment. A motor is supported by the exciter frame so that the exciter frame and motor define a frame center of gravity. The motor includes a rotating shaft defining a shaft center of gravity. The prime mover is positioned with respect to the exciter frame such that the shaft center of gravity is substantially coincident with the exciter mass center of gravity, thereby to minimize movement of the exciter mass assembly in unintended directions.

Abstract: In order to provide the capability of distributing a material that is conveyed, a vibratory distribution conveyor includes a deck having a distribution edge. The distribution edge extends between an inlet end and an end remote therefrom and the deck is subjected to vibratory motion to cause material to be conveyed from the inlet end toward the end remote therefrom. With this arrangement, the declination of the deck is controlled about a longitudinal axis to control the distribution characteristics of the conveyor.
