Eriez - Model HVF -Mechanical Heavy Duty Vibratory Feeders
Eriez HVF mechanical feeders are straight-forward, rugged, vibrating machines that move high volumes of bulk materials reliably and economically. The feeder is a two-mass vibrating system, spring coupled, excited by a motor-driven eccentric shaft. Adjustable-angle rubber springs transmit the exciting force which can “fine tune” the motion of the trough to optimize the feed rate for a specific application. Our heavy duty line of Brute Force feeders provide a cost effective means to feed or screen large volumes of bulk material for applications where limited feed rate adjustability is required. Brute Force feeders are ideal for applications where limited feed rate adjustability is required. Brute Force feeders are ideal for applications such as coal or stone processing, recycling and scrap recovery. Eriez Brute Force feeders can be provided with unique tray designs for your specific applications.
Feeder tray motion is provided by eccentric weights mounted on synchronized, counter-rotation, twin motors. The motors counteract each other to minimize the isolation problems associated with single centric drive systems. Feed rate can be varied by adjusting the weights. The twin motor drives operate on standard AC power.
Dust-tight construction and splash-proof design make the motors more suitable for dusty, dirty environments, as well as outdoors in rain or snow. Heavy-duty construction and long-life bearings ensure peak, long-term performance.
A variety of sizes and styles can be ordered to match specific application requirements. Tray options include screens, liners, covers and grizzlies.
The remarkably compact, design of the Model HVF feeder presents an extremely low profile requiring minimum headroom for easier installation.
The ability of the specially designed polyisoprene rubber springs to amplify the trough stroke results in low horsepower requirements. Power is provided by a standard three-phase, 230/460 volt TEFC 60Hz motor. Hazardous environment motors are also available.
Adjustable, variable-speed sheaves or variable frequency controls are available to provide feed rate adjustability within acceptable operating frequencies.
