Bunting Magnetics Co. expands line of its stainless steel separation conveyors

New 12-inch diameter unit recovers more stainless steel than ever in zurik applications

NEWTON, KS – Bunting® Magnetics Co., has expanded its line of Stainless Steel Separation Conveyors for the Auto Shredding Residue (ASR) industry with the 12-inch Stainless Steel Separation Conveyor™ (SSSC®). The company successfully introduced its new SSSC units at ISRI 2017 in New Orleans last spring and recently received a patent for its innovative magnetic design. Not one to rest on its laurels, the company will introduce the second-generation enhancement to the original SSSC design at ISRI 2018.

This innovative machine expands the company’s reach in the ASR industry for the separation of work-hardened stainless steel, as well as the purification of zurik fraction and in wire-chopping applications. Bunting, the leader in moving, removing and holding metal, is the inventor of stainless steel separation. The company continues to deliver game-changing solutions for the recycling industry with its new for larger stainless recovery.

The SSSC is a natural progression from Bunting’s High Intensity Separation Conveyor® (HISC®), which was the first of its kind in the industry and does an outstanding job separating smaller fraction stainless steel. Competitors introduced similar units to HISC, which do a comparable job in the smaller (less than 1.5 inch) stainless steel separation in the past two years.

The original SSSC has been tested in the field for a year, giving Bunting engineers an opportunity to make significant improvements over the original design. “The 12-inch diameter gives a stronger field above the belt and the larger diameter conforms better to the larger irregular shredded stainless steel, which gives it a better chance to hold onto and recover the larger pieces,” said Don Suderman, Product Manager, Material Handling.

“It pushes the extreme high gauss field higher above the belt into the larger irregular pieces of shredded stainless steel metals,” Suderman explained. “The patented circuit arrangement also creates a larger high intensity, collective flux field pattern, which holds on to those pieces far better than anything before this.”

The new SSSC offers even better separation, holding as much as 94 percent of stainless steel. The heart of the system is the magnetic circuit design, which utilizes a revolutionary configuration of high-strength neodymium magnets. It attracts, holds and extracts work-hardened, irregularly shaped stainless steel – up to five inches in size – from the product recycling stream.

The unique, high-intensity circuit design provides maximum holding force and the ability to catch paramagnetic, work-hardened stainless steel at larger sizes that were previously impossible to separate. It truly raises the bar by leveraging new designs and technology and fortifies Bunting’s leading position in the recycling industry.

Recyclers can also attain the purest product possible with the SSSC in several other applications, including insulated copper wire (ICW) purification, during which the machine pulls out stainless steel shielding of chopped wire; cleaning stainless steel contamination from wire and steel wire connectors.

“Even the smallest bits of stainless steel can cause damage to equipment down the product stream and lower the value of recycled product,” explained Suderman. “It’s imperative that we help our customers achieve maximum purity and our family of stainless steel separation conveyors does just that.”

Bunting engineers incorporated several design features to maximize the SSSC’s functionality: a tough, long-lasting urethane belt with 3/16” stainless steel sideguards to seal off and contain the flow; heavy-duty 3/16 inch stainless steel construction with forklift slots for easier installation; custom sizes available up to 78 inches (2 meters) wide and 144 inches (3.65 meters) long to fit any application; and now, two pulley diameters for extreme effectiveness; optional variable frequency drive to optimize separation for belt speeds between 60 and 200fpm; and an optional splitter to separate the stainless steel fraction and non-magnetic material.
