Bunting Magnetics Introduces Eddy Current Separator

Bunting Magnetics Co., Newton, Kan., has designed and created a new Eddy Current Separator (ECS) as part of its expanding Material Handling product line. The ECS features what the company calls an innovative rotor that maximizes gauss intensity on the belt surface and provides separation of nonferrous materials.

“Our history of creating the highest quality products in the industry has now been extended to include eddy current separators,” states Robert Bunting, Bunting Magnetics owner and CEO. “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.”

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 a urethane belt and a carbon fiber epoxy shell.

“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,” says Don Suderman, Bunting’s product manager for material handling. “The combination of a powerful rotor and compact design optimizes the eddy current forces, separation efficiency and product throw.”

The company says the ECS attains a high recovery rate and provides customers with cleaner materials. Also, the eccentric core is designed to be rotated to provide effective amount of product throw, based on the material and application being used.

“Our eddy current separator is ideal for multiple recycling industries,” says Suderman. “This includes plastics, glass, e-scrap, mixed metals, incineration and auto shredding. For municipal solid waste operations, the ECS can reach a 97 percent recovery rates of aluminum cans from commingled recyclables.”

A key design feature of the Bunting ECS is easy maintenance, the company says. The design includes a drop-down side panel that can be lowered by one person, with one tool, for a quick and easy belt change. The result is a belt change that takes just 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 provides a variable 100 to 300 fpm (feet per minute) belt speed to maximize separation. The ECS drive comes complete with two variable frequency drives (VFD) to program the ramp up of starting the machine.

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

Bunting ECS units are available in 24-inch, 36-inch, 48-inch and 60-inch widths and a 96-inch length. The 24-inch wide may be common in the glass recycling industry and the other three sizes in municipal, plastic, electronic scrap and metal recycling industries, depending on the capacity requirement.

The splitter box features adjustable side closures and an adjustable divider vane to control the direction of 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.
