Auto recycling facilities are a common setting for the use of magnets. They are used in various applications to cull metal from other materials, whether used in conjunction with another tool or as part of some other sorting process. Regardless, the overall goal is to increase efficiency and profitability in a material management situation.
Bunting Magnetics has introduced patented technology to the ASR industry in the last two years that magnetically separates 300 series stainless steel from Zurik streams.
“We call this line of high intensity magnetic separation conveyors our SSSC: stainless steel separation conveyors. This unique, patented magnetic circuit is capable of pulling out and recovering most sizes of 5” minus shredded stainless steel materials. Different size units are available, depending on whether it is a small, mid or large fraction stream and flow rate,” explained Don Suderman, product manager for recycling equipment.
Units are built in sizes from 36 to 78” wide and handle flow rates from 3,000 to 12,000 lbs. per hour. Field separation recovery efficiencies vary between 84 to 98 percent – depending on various system factors.
System factors that affect the ability to attract, hold and separate 300 series stainless steel include: the degree of work hardening from the shredding process, the alloy of stainless steel, the gage or thickness of the stainless, the fraction size being processed and the amount of dirty debris mixed in the stream.
Suderman stated, “Certainly, a cleaner fraction stream of debris with some upstream air aspiration is very beneficial. Fortunately, the 302 and 304 stainless steel varieties are two of the easiest types to work harden and magnetically separate, and the highest volume types found in most Zurik streams. It is a challenge in the ASR industry to recover 300 series stainless steel in an economical way and in the purities required for domestic sales. Most of this dirty Zurik material was shipped to China for years, at very low prices, before that door closed this past year. Now, auto recyclers are forced to search for economical, effective separating solutions for these stainless steels, at a purity level required for domestic sale. That in turn brings a much higher value to the product.”
This newly patented, high intensity, magnetic technology offers a way for auto recyclers to convert their “what do we do with this” Zurik fraction into profitable sales. “There has never been a better time to use one of our SSSCs. The products have been very effective in helping facilities recover stainless material while also achieving 98 percent purity, thereby capturing the highest domestic market prices available,” said Suderman.
The complete line of heavy industry equipment manufactured by Industrial Magnetics is designed for separation of ferrous and nonferrous metal for a variety of applications and industries.
“Our products are used in industries such as auto shredding, recycling, waste recovery, mining, MRFs, C&D, incineration, electronics recycling and bulk material processing. We offer a series of overhead magnets with a wide array of features to match application and budget requirements. Our SMS unit offers optimum operating efficiency with a continuous cleaning belt to keep the magnet face free of collected metal. The compact design of the SMS makes it ideal for use on portable, size reduction equipment,” stated Dennis O’Leary, chief business development officer. He reports that the manual lean SPMC unit is a less costly alternative.
Suspended electromagnets are designed to deliver peak ferrous metal separation performance. The deep reaching magnetic field can be ideal for applications that require increased suspension heights due to product burden depth.
Powerful permanent separation pulleys are typically installed as head pulleys in conveyor system applications. They provide effective, automatic and continuous removal of tramp metal from a material flow. Continuously self-cleaning drum separators provide ferrous metal removal from dry, bulk products in free-flowing processing systems.
The company’s Javelin™ eddy current separator (ECS) provides high recovery rates (97 percent+) and low operating costs. The product has the strongest and deepest field available, providing a farther throw and higher and cleaner recovery rates.
“Our ECS is in use at major facilities around the world with excellent results. We guarantee the cleanest split of commingled materials and world-class return on investment, thanks to a cleaner end product,” O’Leary said.
All Industrial Magnetics products are built in the USA and designed to: protect vital processing equipment from metal damage; improve product purity and quality; reclaim valuable ferrous and nonferrous metal; reduce product liability.
Moley Magnetics’ 2-in-1 Magnet Grapple is a grapple with a magnet in the center, ranging in sizes from 32 to 50” in diameter.
“While most auto recycling yards own a grapple and a magnet, their advantages differ. While a grapple can grasp a large amount of material quicker than a magnet, the grapple picks up a lot of dirt and leaves plenty of small, recyclable material behind, resulting in less profit. Once a scrap pile has been driven over a handful of times, some metal may be pressed into the ground but a magnet can be used to collect the remaining ferrous metal. Switching between magnet and grapple use can be tedious, time consuming and impractical. This problem can be resolved by using our multi-purpose tool,” said Ron Slaby, vice president, sales.
He claims the Moley 2-in-1 Magnet Grapple is paramount in maximizing efficiency as a time saver and money maker, as well as its contribution to a more sustainable environment by removing material from the ground that shouldn’t be there. Moley manufactures magnets, grapples, wheel removers, shears, shredders, granulators and generators for auto recycling and scrap use.
“We’ve been delivering high quality products for the past 10 years, and will continue to evolve and innovate as the industry progresses,” Slaby added.
