Ohio Magnetics is continuing to offer its PRO magnet inspection program, which offers on-site magnet inspection services to customers who operate at least 10 of the firm’s lifting magnets.
Ohio Magnetics, based in Maple Heights, Ohio, says the PRO program has been tailored to help optimize the efficiency of production while minimizing costs and maximizing safety. While its steel service center, mill and scrap yard clients predominantly own lifting magnets, the company also sells and services magnetic separation units used by recyclers and concrete crushing plant operators.
The firm says its program contributes to the bottom line of participants by reducing operating costs, extending the life of magnets and maximizing magnet uptime. While Ohio Magnetics equipment is the focus of the program, the firm also inspects magnets and separation equipment from other manufacturers, according to sales manager Tim Schuh.
Whether as part of the PRO program or via another scheduled appointment, Schuh says an Ohio Magnetics inspection involves experts who conduct on-site visual inspections and electrical readings that are essential to thoroughly evaluate each magnet.
“During inspections, we look for signs of excessive wear that could cause failure or lead to unsafe conditions," Schuh tells Recycling Today. "The case condition, leads, connections, suspension system and terminal box are all examined. Our experts also capture coil resistance, current and voltage, along with impedance of the magnet.”
Although magnets in recycling applications can operate in harsh conditions, Schuh says annual inspections typically are adequate for most types of magnets. "Our team can suggest whether additional inspections are required," he adds.
A lifting magnet in a large-tonnage application can experience excessive wear to its suspension system, chains, pins and yokes, Schuh says. Of models operating outdoors, Schuh tells Recycling Today that water also can leak into the magnets through cracks in the case or through terminal boxes.
After the inspection, Ohio Magnetics personnel provide complete postinspection documentation.
