Eriez HVF Mechanical Feeders have a compact, straight-line design and quick flow rate for optimal performance. The feeder is 
a spring coupled, two-mass vibrating system with a motor-driven eccentric shaft. The hand-wheel adjustable variable-speed sheaves help to achieve an accurate control of flow rate, which can be up to 60 feet/minute. They can also control up to 2,000 tons of material per hour. The adjustable-angle rubber springs can be removed and replaced quickly and are also designed to amplify the trough stroke, resulting in low horsepower requirements. The motion of the troughs can be adjusted to accommodate the flow rate for specific applications and a variety of trough sizes and types are available.
