Eddy Current Separator


Bunting® Magnetics Co. has designed and created a new Eddy Current Separator (ECS) as part of our expanding Material Handling product line. Our ECS product features an innovative rotor which maximizes gauss intensity on the belt surface and provides superior separation of non-ferrous materials.

“Our history of creating the highest quality products in the industry has now been extended to include Eddy Current Separators,” stated Robert J. Bunting, the company’s owner and Chief Executive Officer. “This addition to our product offering gives us the ability to provide complete systems for recycling operations around the world. Beginning with our powerful magnetic separation equipment, Bunting® now offers a diverse lineup that includes magnets, metal detectors, conveyors, magnetic pulleys and more. From start to finish, we can help our customers achieve a high rate of recovery for recycled material and protect their processing equipment as well.”

Superior Engineering

The Bunting® ECS core is designed to provide a high level of gauss intensity to enhance separation on a wide range of nonferrous materials and part sizes. It is protected with the tough urethane belt and a carbon fiber epoxy shell. From aluminum cans to kitchen pots and pans, our ECS units do an excellent job of throw and separation.

“Our clean, low profile streamlined design has been crafted by using advanced magnetic finite element design software to optimize the gauss flux density in the working area above the belt,” Don Suderman, Bunting® Product Manager for Material Handling said. “The combination of a powerful rotor and compact design optimizes the eddy current forces, separation efficiency and product throw.”

Our ECS attains a high recovery rate and provides our customers with cleaner materials, which is the bottom line result everyone is seeking. Also, the eccentric core is designed to be rotated to provide the most effective amount of product throw based on the material and application being used.

“Our Eddy Current Separator is ideal for multiple recycling industries,” stated Suderman. “This includes plastics, glass, e-Scrap, mixed metals, incineration and auto shredding. For municipal solid waste operations, the ECS can reach a 97% recovery rates of aluminum cans from comingled recyclables.”

Maintenance Friendly

One of the key design features of the Bunting® Eddy Current Separator is how easy it is to maintain. Our efficient design includes a drop down side panel which can easily be lowered by one person for a quick and easy belt change. In fact, only one tool is required to loosen the belt, drop the side panel, replace the belt, re-track the belt and be back up and running in minutes!

The rubber lagged inverter duty motorized drive pulley at the in-feed provides for exceptional driving force, variable speed drive and a clean out-of-the-way design. It is easy to work on when needed and it provides a variable 100 to 300 fpm belt speed to maximize your separation. The ECS drive comes complete with two variable frequency drives (VFD) to program the ramp up of starting the machine.

Built to Last

The ECS unit has the highest quality urethane endless belt with 1 ½” urethane flexwall and three (3) sweeper cleats to help kick off ferrous contamination. In addition to the flexwall, the ECS has a secondary brush seal outside the flexwall which serves as a double seal of protection to prevent material from getting inside the conveyor frame.

Bunting® ECS units are available in 24”, 36”, 48” and 60” widths and 96” long. The 24” wide may be common in the Glass Recycling industry and the other three sizes in Municipal, Plastic, E-Scrap and Metal Recycling Industries depending on the capacity requirement.

Splitter Box

Our Splitter Box features adjustable side closures and an adjustable divider vane. This allows you to control the direction of your product flow. There are side extenders on the Splitter Box to widen the range of it. These items can be custom built to accommodate any height requirement.
