Equipment Spotlight | APR 2020 Magnets

by MARY M. THORNTON

Magnets are used in a variety of ways in many metal recycling operations. Product types vary, depending on the type of processing involved, but optimal recovery is always the ultimate goal. Product configurations vary as well, and it is important to review all options available, so that the right magnet is paired with the task at hand.

Bunting’s patented SSSC (Stainless Steel Separation Conveyor) uses a patented magnetic circuit design of high intensity neodymium magnets to maximize stainless steel recovery and removal in applications such as general recycling, auto shredding and wire chopping streams. The SSSC allows for recovery of up to 98 percent of small and mid-fraction 300 series stainless steel and up to 94 percent of large fraction stainless steel from ASR zurik lines. The SSSC provides maximum removal of stainless steel and ferrous dust from wire fraction and the purest zurik, maximizing scrap metal recovery profitability.

“The SSSC is the only product available in the modern recycling market that achieves such high stainless steel recovery levels. Bunting’s on-site testing facilities allow us to test how your material interacts with the SSSC in real time, to provide you with real results. We offer extensive custom design options and our engineers will work with you to deliver the optimum piece of equipment for your facility,” said Mike Wilks, global marketing director.

He added, “There are multiple SSSC features designed to maximize separation efficiency and streamline operations. It is equipped with 8” and 12” diameter patented high intensity neo magnetic circuit head pulleys, capable of holding all sizes of 300 series stainless steel, as well as VFD controllers operating between 30 and 120 fpm to deliver effective separation. General capacities run about 1,000 lb./hr./ft. width on small fraction, 1,500 lb./hr./ft. on mid-fraction, and 2,000 lb./hr./ft. on large fraction. Optional features for the SSSC include a patented air knife, discharge hood, and vibratory feeder. Generally, when recycling, product purity directly correlates to profitability and higher purity product results in significantly greater profit. Product that is excessively contaminated can sometimes result in no profit at all. To maximize your purity and profitability, contact Bunting today.”

“At Moley Magnetics we build, sell and service magnets for the wide range of materials that arrive daily in scrap yards. The scrap and demolition industries have many unique and demanding applications for magnet systems. These magnets sweep, sort, separate, load and unload every day. The demand is for a magnet system that is durable and dependable. Magnet systems are a crucial part of most ferrous recycling operations and so, the purchase and maintenance of magnet systems is a major focus. We offer a variety of magnet systems designed for top operational efficiency and lasting durability. These magnets systems operate on 230 volts DC, 12 volts and 24 volts and systems can be powered by hydraulic driven generators or batteries. Our magnet sizes available range for 18” up to 72” in diameter,” Jeff Seavers, outside sales manager, stated.

“With the ever-increasing trend in magnet system operation tracking, owners can choose the Moley MagStar hydraulic generator system with self-diagnosing fault. Through the HDMI, the operator is notified in the event of a shorted magnet cable or a blown fuse. With the use of the MagStar clients have a safe, cost effective and easily maintained generator and controller as part of the magnet operation. The product is available in sizes from 9kW to 30kW,” Seavers said.

Industrial Magnetics and Javelin supply products for the removal, recovery, and separation of ferrous metals, nonferrous metals, and certain grades of stainless steel. Equipment is available in a range of sizes to fit the footprint and capacity requirements for any user. Custom sizes and other features are available upon request. “In the scrap industry, customers use our drum magnets, magnetic pulleys, and suspended magnets to remove ferrous metal. We offer eddy current separators for the recovery and separation of nonferrous metals, and our magnetic stainless steel conveyor separators perform the removal, recovery, and separation of lightly ferritic stainless steel,” explained Jason Miller, vice president, engineering, Javelin.

“The processing volume of our customers varies based on the application. Our typical customer base processes between 5 to 20 tons per hour. During the sales and engineering phase for our equipment, we strive to gather as much information for the application involved, as possible. This provides the user with the best possible product fit and also helps prevent and eliminate issues during equipment installation and setup. This process also may involve testing equipment – using customer material – in our lab. This gives us the opportunity to see how our equipment will likely perform, in a simulated customer environment.

Recently, it has become more common for us to see customers who wish to recover and refine more of the metals that they had previously sent to either a landfill or had classified as a mixed metal package. For example, we developed our MSSC magnetic separators specifically for stainless steel recovery and separation, as those metals were typically sold for a lower price in a mixed metal package. As our industry and technologies continue to evolve, our equipment offers the opportunity for higher recovery and purity rates, which allows our customers to increase revenue,” commented Miller.

Industrial Magnetics has manufactured and sold magnetic products since 1961 and Javelin has manufactured eddy current separators since 2009. The Javelin brand was acquired by Industrial Magnetics in 2017. The firm serves the following markets: metal recycling, MRF recycling, MSW, e-scrap, food processing, waste-to-energy and peripheral industries as well.
