Abstract
An apparatus for use in sorting granular materials which includes a bin having an outlet. A conveyor is disposed beneath the outlet of the bin. A pin is provided having a first end and a second end. The first end is affixed to the conveyor. The second end extends into the outlet of the bin. A motor is used to vibrate the conveyor. The pin vibrates in the outlet of the bin as the conveyor vibrates, thereby promoting a flow of granular material from the bin onto the conveyor in direct proportion to the rate of vibration of the conveyor.
