A vibratory conveying feeder includes a trough mounted by springs to a base with a vibratory driver bonded to the base and connected to the trough. The springs include a first vertically oriented spring at a front of the conveyor connected between the base and the trough and a second spring arranged between the trough and the base and arranged along a line about 20.degree. to the horizontal. The second spring is set between 40% to 80% of total spring rate. The base is tapered toward a rear side thereof to allow a plurality of such conveyor feeders to be mounted in a tight circle for delivering material radially outwardly of the center line of the circle in a weighing and distributing operation.
