B-HC Feeders
Eriez High Capacity Feeders
Eriez’ B-HC High Capacity Feeders effectively meter materials for high-demand use. The B-HC line offers the widest capacity range in the industry. Capable of delivering controlled amounts from just a few kilograms to 1,089 metric tonnes (1,200 tons) of bulk material per hour.*
Four models give you the flexibility you need, with the 65, 75, 100, and 120 models.
Industry-Leading Performance
Built for continuous use, each B-HC Feeder is made to handle bulk flows time and time again. With no wear, rotating, or sliding parts, maintenance is minimal. Help reduce downtime with equipment that’s always on the job.
The electromagnetic coil and rare earth armature are a proven design that requires minimal maintenance and extends the life of the feeder. The drive assembly is enclosed, remaining dust and moisture resistant. This extends coil life and allows for continuous use.
Space-Saving Convenience
With a specialised low-profile design, each model of B-HC Feeders has a smaller physical footprint. Ideal for head load applications below hoppers, it meters material to belt conveyors, screens, crushers and elevators. While the throughput increases, valuable spaces are saved — a fit for virtually every environment.

Variety of Trays
Eriez offers a wide variety of tray and trough sizes and types for specific applications. Flat, open trays are common but tubular trays, and screening trays are available. Other custom options offered include inlets, outlets, tray covers,
cleaning ports.
Typical construction material consists of mild or stainless steel. For harsh applications such as glass cullet, limestone or other abrasive products, replaceable tray liners such as UHMW, stainless steel, AR steel, chrome carbide or other materials can be provided.
Superior Drive Design
The Eriez Full Wave drive design is powered by alternately opposing and attracting magnetic forces. This rapid, automatic switching causes a vibration, which provides a simple yet powerful solution to difficult material feeding applications. Traditionally, competitors have used an inefficient attract-release design, in which an electromagnet pulls the tray in one direction and the feeder springs cause the tray to snap back in the opposite direction.
The Full Wave drive has the effect of progressively closing the magnetising circuit through the electromagnet core, providing a progressively increasing magnetising force upon the permanent magnet. The demagnetising force is very minor, since the action described also has the effect of progressively opening the demagnetising circuit. On the opposite side of the sine wave the polarities of the electromagnet are reversed. The armature is driven in the opposite direction, and again there is a net magnetising force on the permanent magnet. There is always a predominant magnetising force impressed upon the permanent magnet that prevents it from ever losing its strength.
Since the amplitude of vibration depends directly upon the forces applied at the poles, and since these forces depend directly upon the applied AC voltage, simple variation of the AC voltage from zero to maximum results in similar amplitude variation from zero to maximum. The basic simplicity of a drive powered by alternately opposing and attracting magnetic forces assures low maintenance. There are no sliding or rotating parts. The positive driving force of Eriez units provides stability, control,
and unexcelled accuracy.
