ABSTRACT:
An assembly for controlling delivery of material from a bin opening includes a movable bin gate for closing the bin opening and providing a high flow rate of material when the movable gate is open, wherein a low flow aperture is formed in the bin gate to provide a low flow rate of material when the bin gate is positioned such that only the low flow aperture is open. A two-stage flow enhancer within the bin includes a first stage for impelling material in the direction of the low flow aperture and a second stage for impelling material to exit through the low flow aperture. A controller controls operation of the bin gate to adjust a flow rate of material from the bin opening.
