EQUIPMENT SPOTLIGHT | MAY 2025 Magnets

Magnets, commonly used in metal recycling settings to lift out large and small metal components, are available in a variety of configurations, due to the varying stages of recovery that may be involved. In just the U.S., Fact.MR notes that the scrap metal recycling market is poised to reach a value of $15.6 billion by the end of 2032. The sheer volume of material recycled flows from a wide array of sources.

Dings Company Magnetic Group

Dings Company Magnetic Group has manufactured a full line of magnetic separation equipment for the recycling industry for over 125 years. “Whether our customers are recycling concrete or municipal waste, the reliable removal of ferrous metal early in the process enhances the purity of the recycled material and often defends critical processing equipment from damage caused by tramp metal,” stated Steve Tanzilo, sales manager.

“When space is limited relative to your processing line or mobile unit, our overhead, self-cleaning permanent magnet is an ideal solution for recovering ferrous metals. All of our unique, overhead, permanent magnets employ Dings’ flux control (DFC) circuit design. The DFC design improves separating performance by creating a deeper, stronger and more uniform magnetic field than those found in other, ‘conventional’ magnetic designs. We accomplish this by strategically placing blocking magnets in between the magnetic poles and so redirecting magnetic flux — commonly lost in other designs — back into your product as working force.”

“As an engineering driven company, users can rely on expert support from Dings to convert their application details to a recommended self-cleaning magnet that is sized and positioned to meet their specific magnetic separation needs. The recycling trade can count on Dings for high quality equipment in all phases of the process. Our durable deep draw drums are designed for high volume ferrous separation and we also offer magnetic pulleys for continuous separation of conveyed material. Our other self-cleaning, overhead magnets – whether permanent or electro – provide efficient collection of ferrous materials. Also, our eddy current separators are ideal for separation of aluminum, copper and other valuable nonferrous from cardboard and plastic material streams,” Tanzilo added.

Pat Markiewicz, president of Magnetic Systems International (MSI), explained that the company specializes in problem solving. MSI offers suspended, auto-clean, permanent (SAP) magnets in a multitude of strengths and sizes for the metal recycling and other industries. “We strive to ease any pinch points that our customers might encounter and we’ve been in the business of designing and manufacturing magnetic separation equipment for over 30 years. During that time, we have seen a steady increase in demand for suspended magnets, both permanent and electromagnetic. Whether we are helping a customer that has a 12” belt with minimal burden, or a 72” belt piled with crushed C&D debris, we offer the right permanent magnet to exceed our customer’s needs.”

As the world’s need for more rare earth minerals continues to grow, Markiewicz noted that MSI has stepped up to the plate by offering their compact suspended electromagnets. “Large scale scrap operations with a variety of belt sizes and speeds as well as finer purification plants have really benefited from utilizing our electromagnets in both manual and self-clean options. Through recent advancements in our designs, we have created a more powerful electromagnet than our competitors, which is provided in compact packaging. These new designs reduce cost related tp weight, labor, and material. This has in turn, allows us to pass along substantial savings to our customers and this is a point of pride for us,” he said.

Sieb Sales & Engineering, Inc. specializes in manufacturing magnet systems for the scrap, steel and railroad industries. “Our circular, 230 VDC electro-lifting magnets range in size from 30” in diameter up to 78” in diameter. All are heavy duty fabricated housings designed for wear and long life. Features include 75 percent duty cycle coils with high strength tested alloy steel chains coupled to the magnet with double ears and chain pins for greater safety. We have been in the magnetic material handling business since 1967,” Ronald Sieb, president, noted.

“Bear in mind, there is much more to hanging a magnet off the end of a crane than some may realize. A lifting magnet is typically used in very rigorous conditions and demands steady, reliable voltage and the controls to match, depending on the application variables involved. We have industry leading experience in working with all types of magnetic material handling systems. Tell us about your specific requirements. Then we will provide suggestions that ensure your machine is equipped with the most productive and cost-effective system, specifically designed for your needs. Once you have what you need in place, our service expertise will be available to you as well. We offer unmatched technical support and stock parts for all manufacturers and types of magnet system equipment. Superior customer service is an integral part of who we are,” concluded Sieb.
