Heavy Duty Vibratory Feeders


HVF Mechanical Vibratory Feeders
Rugged, heavy duty feeders that provide a cost effective means to feed or screen large volumes of bulk material.


Eriez offers different styles of heavy-duty vibratory feeders designed specifically for high volume rugged environments.

Eriez offers different styles of heavy-duty vibratory feeders designed specifically for high volume rugged environments. Whether you are presenting conveyed material to process separation equipment or you need to accurately feed tons of rock at a high headload, Eriez has a feeder solution to match your application.

Our heavy-duty feeders can be found in harsh environments like mining operations, rock quarries, steel mills, glass plants, aggregate and cement plants, slag mills, mineral processing facilities to general high-volume bulk material handling applications needing precise metering of materials.

    HVF Mechanical Vibratory Feeders

    Harsh environments like mining operations, rock quarries, aggregate and cement plants, slag mills, mineral processing facilities are typical applications for Eriez Mechanical Feeders. Their extreme low profile and easy access to components make them well suited to tight spaces.

    Electromagnetic feeders are often mounted below a hopper for high-volume bulk material handling and processing applications where greater precision and accurate metering of material is required.


    Brute Force Mechanical Vibratory Feeders

    Ideally suited to transit material from a belt conveyor to spread the material and present it evenly across the width of tray. Typically, Brute Force feeders are positioned before processing equipment like eddy current separators or sorters.

    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.


    • Adjustable-angle polyisoprene rubber springs
    • Low profile design requires minimum headroom
    • Suitable for high material load applications such as below hoppers
    • Feed rates to 60 ft/minute (18mpm)
    • Adjustable with variable frequency drive
    • Low horsepower requirements
    • Heavy-duty construction for rugged applications
    • Easily replaced standard motors

    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.


    Eriez Heavy Duty Electromagnetic Vibratory Feeders are designed for high volume, controlled feeding applications like glass cullet, ore, aggregates, slag and most any dry bulk solid. These feeders feature our patented energy-saving intermeshed AC operated, permanent magnet drives. Powerful, accurate and highly efficient, this line of vibratory feeders is available in models with capacities to 660 tons (594 MT) per hour*.


    • No wear parts – electromagnetic drive
    • No rotating or sliding parts
    • Ideal for head-load applications below hoopers
    • Suspended or base mounted configurations
    • Energy efficient AC operation
    • Solid-State controls offer variable speed
    • Long-life encapsulated coils
    • Protective enclosed drive elements

    Eriez’ unique and patented magnetic drive circuit provides a simple yet powerful solution to difficult material feeding applications.

    Eriez Heavy Duty Vibratory Feeders means greater productivity at lower cost. In addition, you get all the features that for years have made Eriez Feeders the leaders in quality and dependability.

    *Capacity is based on sand weighing 100 pounds per cubic ft. (1.6 metric tons per cubic meter)


    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 adjstability is required. Brute Force feeders are ideal for applications such as coal or stone processing, recycling and scrap recovery. Eriez BF feeders can be provided with unique tray designs for your specific application.


    • Rugged, heavy duty construction
    • Twin rotary motors for stability
    • Unique tray designs available
    • Quiet operation
    • Easy access to rotary motors
    • Available for hazardous environment applications
    • Available for screening 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 rotary vibrator 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 suitable for dusty, dirty environments, as well as outdoors in rain or snow. Heavy-duty construction and long-lift bearings
