Heavy Duty Feeders

HVF Mechanical 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.

Features:

• 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.

Brute Force Mechanical Vibratory Feeders

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 such as coal or stone processing, recycling and scrap recovery. Eriez BF feeders can be provided with unique tray designs for your specific application.

Features:

• 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
