Industrial Magnetics Repurposes Large Tube Drawer Magnet for Recycling Application
Industrial Magnetics, Inc. (IMI) says their innovative large tube drawer magnet is proving itself to be an industry-versatile magnetic separator. Typically used in the food processing industry for products with difficult flow characteristics, such as flour or powdered sugar, the Large Tube Housing (LTH) magnet has found recent success in a paper recycling operation. The application involves shredding recycled newsprint, grinding it down into pulp and then remaking it into paper. The LTH rare earth magnet was installed after the shredding operation with two key tasks: to catch stray nuts or bolts in order to protect downstream grinding equipment, and to collect metallic fines to ensure a pure, metal-free end product.
“The Large Tube Housing was originally conceived for a soft wheat processor, but we’re still discovering new applications and locations for installing this product,” says IMI product specialist, Brian Hater.
IMI says the LTH is an innovative and powerful separator not only because the tubes are three times larger in diameter than the company’s traditional drawer magnet housing, but also because it’s designed with 52 MGOe rare earth magnet material. It can achieve 23 pounds pull on a 1/2-inch ball, making it the strongest magnetic circuit available for gravity, metered and/or choke feed applications. The unit is offered in both EZ-Clean and Self-cleaning designs for removing collected metal from the magnetic tubes. Several options are available, such as Nedox coated tubes for abrasion resistance or food-grade silicone seals, and custom sizes and transitions can be manufactured to fit exact application requirements.
