In the aggregate, mining, and minerals industries, crossbelt magnets play a critical role in safeguarding equipment like crushers, screens, and conveyors from damage caused by tramp ferrous metal. However, no single magnet fits all applications. Each operation has unique requirements, and selecting the right crossbelt magnet is essential for optimal performance and long-term reliability.

The Crossbelt Magnet: A Workhorse of Efficiency

Since the early 1980s, Bunting has been at the forefront of developing permanent crossbelt magnets, revolutionizing the way ferrous metals are removed from material streams. These magnets have evolved over time, with improvements in magnetic materials and manufacturing techniques enhancing their efficiency and effectiveness.

Designed as a permanent system, crossbelt magnets consist of a strong magnet block mounted within a durable frame, paired with pulleys and a self-cleaning rubber belt. As materials pass beneath the magnet, it attracts and removes unwanted ferrous contaminants, ensuring smoother operations and reducing downtime.

The choice between a permanent or electro-magnetic system depends on several factors, including conveyor width, material depth, and the type of tramp metal present. Understanding these variables helps ensure the best match for your specific application.

Crossbelt Models and Applications

Bunting offers a range of crossbelt magnets tailored to different industrial needs. The OCW Heavy Duty Oil Cooled Electro Crossbelt Magnetic Separator is ideal for high-capacity operations, providing powerful separation even under heavy loads. It’s particularly suited for deep troughed conveyors in recycling and mining environments, available in widths ranging from 36” to 84”.

The ACW Heavy Duty Air Cooled Crossbelt Magnetic Separator is another top-tier option, offering efficient performance with minimal maintenance. Its air-cooling system ensures reliable operation without the need for oil, making it a popular choice for facilities that prioritize ease of use and long-term durability.

Bunting’s Heavy-Duty Electro Crossbelt Magnetic Separators represent the pinnacle of our product line, delivering exceptional magnetic strength and versatility. These systems are designed for large-scale operations, capable of extracting ferrous material from deep troughed conveyors efficiently. They come in standard models suitable for belts ranging from 24” to 78½”, making them adaptable to a wide range of setups.

How to Choose the Right Crossbelt Magnet

Selecting the appropriate crossbelt magnet requires a detailed understanding of your operation. Factors such as the purpose of metal removal (e.g., protecting downstream equipment), the size and shape of tramp metal, and the characteristics of the conveyed material all influence the decision.

Bunting’s team of experienced engineers works closely with clients to evaluate these factors and recommend the most suitable solution. Whether you’re dealing with small particles or large debris, we provide customized options that meet your specific needs and maximize operational efficiency.

With decades of experience and a commitment to innovation, Bunting continues to lead the industry in magnetic separation technology. Our solutions are designed to enhance productivity, reduce maintenance costs, and improve safety across mining and aggregate operations.
