Eriez HVF mechanical feeders are simple and rugged vibrating machines that move high volumes of bulk materials reliably and economically. These low-profile feeders have a compact, straight-line design and quick flow rate for optimal performance, according to the manufacturer.

The Eriez HVF mechanical 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 for the feeders, which can be up to 60 ft. (18 m)/minute. HVF feeders also can control up to 2,000 tons (1,814 t) of material per hour.

The feeders’ adjustable-angle rubber springs can be removed and replaced in less than two minutes and also are 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.

A standard three phase motor mounted behind the base frame of the HVF feeder is belt connected to the factory set variable-pitch sheave, which drives the eccentric shaft at approximately 1,100 rpm. The vibratory motion created by the shaft is amplified by the polyisoprene springs to which the tray is connected.

“These high quality units are built to last,” said Rob Yandrick, Eriez product manager — vibratory. “The heavy-duty construction of the HVF feeders will guarantee this product has a long life at your plant, even under the most difficult operating conditions.”
