Heavy Duty Feeders

Eriez B-HC High Capacity Electromagnetic Vibratory Feeders 

Eriez’ B-HC High Capacity Feeders boast the widest capacities in the industry. They feature a drive and electromagnetic coil design with a stronger Rare Earth permanent magnetic armature assembly. With four different models, their feed capacities range from 330 Tons (300 MT) to 1100 Tons (982 MT) per hour. 

These rugged electromagnetic feeders are ideal for metering material to belt conveyors, screens, crushers, and elevators. 

• High-power electromagnetic drive with Rare Earth armature 
• No wear, rotating, or sliding parts  
• Energy-efficient AC operation 
• Standard and custom-engineered tray designs for your specific applications 
• Optional abrasion-resistant steel or UHMW liners  
• Solid-state controls offer variable speed precise feed rate control* with accelerometer feedback for added protection 

Eriez unique AC drive applies power on both the forward and reverse direction of the feeder tray, giving superior linearity and control compared to an attract-release design.  

The simplicity of Eriez’ drive powered by alternately opposing and attracting magnetic forces assures low maintenance and accurate feeding. There are no sliding or rotating parts, power consumption is low, and installation is easy.  

The drive assembly is dust and moisture resistant, which extends coil life.  

In addition to the wide variety of standard trays, special trays such as tubular, covered, screens, and various liners, etc. are available.  

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

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.
