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 design fits all applications. Each operation has unique requirements, and selecting the right permanent crossbelt magnet is essential to ensure efficiency, safety, and long-term performance.

The Crossbelt Magnet: A Workhorse of Efficiency

Since the early 1980s, Bunting has been at the forefront of developing and manufacturing permanent crossbelt magnets, revolutionizing the way ferrous metal is removed from raw materials. These magnets have evolved over time, with improvements in magnet materials and construction techniques significantly boosting their effectiveness. Today, they remain a vital component in many industrial processes.

Designed with a strong, permanent magnet block mounted on a durable frame, crossbelt magnets feature a self-cleaning rubber belt that rotates over pulleys. As material passes beneath the magnet, it captures and removes unwanted iron contaminants, preventing costly damage downstream. The choice between permanent and electro-magnetic systems depends on factors such as conveyor size, material depth, and the type of tramp metal present.

Crossbelt Models and Applications

Bunting offers a wide range of crossbelt magnets tailored to different operational needs. One of the most powerful options is the OCW Heavy Duty Oil Cooled Electro Crossbelt Magnetic Separator, designed for heavy-duty applications. It delivers high magnetic strength, allowing for efficient separation even in deep troughed conveyors. This model is ideal for recycling operations and can be installed across conveyor widths ranging from 36” to 84”.

The ACW Heavy Duty Air Cooled Crossbelt Magnetic Separator is another top-tier option, offering reliable performance with minimal maintenance. Its air-cooling system ensures consistent operation without the need for frequent oil changes, making it a cost-effective solution for many facilities.

For the most demanding environments, Bunting’s Heavy-Duty Electro Crossbelt Magnetic Separators provide unmatched power and flexibility. These units are built to handle deep material loads and can be configured to fit conveyor belts up to 78 ½” wide. Whether placed inline or over head pulleys, they deliver superior separation performance in challenging conditions.

How to Choose the Right Crossbelt Magnet

Selecting the appropriate crossbelt magnet involves understanding the specific needs of your operation. Factors such as the goal of separation (e.g., protecting equipment), the size and shape of tramp metal, and the characteristics of the conveyed material all play a role in the decision-making process.

Bunting’s team of experienced engineers works closely with customers to evaluate these factors and recommend the best solution. With decades of industry experience and a focus on customized solutions, we help ensure that every installation is optimized for performance and reliability.
