In the aggregate, mining, and minerals industry, permanent crossbelt (overband) magnets play a critical role in safeguarding key equipment like crushers, screens, and conveyors from damage caused by tramp ferrous metal. However, no single magnet fits all applications. Different designs are available to suit specific operational needs, and selecting the right one requires a deep understanding of the setup and requirements.

Bunting has developed a wide range of crossbelt magnets tailored for various industries, ensuring that each customer finds a solution that matches their unique challenges. Whether you're dealing with heavy-duty material flow or high-precision separation, there's a magnet designed for your operation.

The Crossbelt Magnet: A Workhorse of Efficiency

Since the early 1980s, Bunting has been at the forefront of developing and manufacturing permanent crossbelt magnets, setting new standards in industrial magnetic separation. These devices have evolved over time, thanks to improvements in magnet materials and production techniques, making them more effective and reliable than ever before.

Designed to remove unwanted ferrous metals from conveyed materials, crossbelt magnets use a permanent magnet system combined with a rotating self-cleaning belt. This setup ensures continuous operation without frequent maintenance, making it ideal for harsh environments found in mining and aggregate operations.

The choice between a permanent or electro-magnet depends on several factors, including conveyor width, material depth, and the type of tramp metal present. Each option offers distinct advantages, and the right selection can significantly improve both efficiency and safety in your facility.

Crossbelt Models and Applications

Bunting’s OCW Heavy Duty Oil Cooled Electro Crossbelt Magnetic Separator is built for demanding environments where maximum performance is required. With strong magnetic fields, this model can handle wider gaps and heavier loads, making it ideal for deep troughed conveyors commonly used in recycling and mining applications. It comes in multiple sizes, fitting conveyor belts ranging from 36” to 84” in width.

The ACW Heavy Duty Air Cooled Crossbelt Magnetic Separator is another powerful option, offering high performance with lower maintenance needs. Its air-cooling system makes it an efficient choice for facilities looking to reduce downtime while maintaining strong magnetic field strength. It effectively captures fine ferrous particles, improving product purity and reducing wear on downstream equipment.

Bunting’s Heavy-Duty Electro Crossbelt Magnetic Separators represent the pinnacle of our engineering expertise. These units provide exceptional magnetic power and versatility, suitable for even the most challenging applications. They are ideal for deep troughed conveyors and can be installed inline over head pulleys or across conveyor belts up to 78.5” wide.

How to Choose the Right Crossbelt Magnet

Selecting the right crossbelt magnet involves considering several key factors, such as the purpose of the separation—whether it’s for plant protection or product purity—and the characteristics of the tramp metal, like size, shape, and type. The properties of the material being conveyed also play a significant role in determining the best fit.

Bunting’s team of application engineers works closely with customers to evaluate these variables and recommend the most suitable magnet for each situation. Their experience and technical knowledge ensure that every installation is optimized for performance, reliability, and cost-effectiveness.

With decades of innovation and a commitment to delivering customized solutions, Bunting continues to lead the way in magnetic separation technology for the mining and aggregate industries. Our goal is to help you achieve greater efficiency, safety, and productivity in your operations.
