Abstract
Apparatus for continuous flow weighing of a flowable material includes a pair of sequential conveyors. A first, control conveyor moves material from an inlet to a discharge point. A second, weighing conveyor is mounted for pivotal movement about a horizontal axis at its inlet end. The pivot point is positioned below the discharge of the control conveyor. The outlet end of the weighing conveyor is suspended from and weighed by a load cell. Electronic control circuitry monitors the material transport rate of the weighing conveyor which, in combination with the output of the loadcell, is used to determine the weight flow rate of material being discharged from the weighing conveyor. The material transport rate of the weighing auger is adjusted to result in a preselected weight flow rate.
