In the aggregate, mining, and minerals industry, equipment protection is a top priority. One of the most effective tools for safeguarding critical machinery like crushers, screens, and conveyors is the permanent crossbelt magnet. These devices are essential for removing tramp ferrous metal—unwanted metal objects that can cause severe damage if left unchecked.

However, no single solution works for every operation. Different applications require different designs, and choosing the right magnet involves understanding the specific needs of your process. That’s why Bunting has developed a wide range of crossbelt magnets tailored to various industries and environments, ensuring optimal performance and reliability.

The Crossbelt Magnet: A Reliable Workhorse in Industrial Settings

Since the early 1980s, Bunting has been at the forefront of magnetic separation technology. As one of the first companies to develop permanent crossbelt magnets, they have since supplied thousands of these systems globally. While the basic concept remains the same, continuous improvements in magnet materials and manufacturing techniques have significantly enhanced their efficiency and durability.

Crossbelt magnets are designed to work seamlessly within conveyor systems. They consist of a powerful magnet block mounted in a strong frame, with a rotating self-cleaning belt that lifts and removes unwanted metal from the material being transported. This ensures that harmful tramp metal doesn’t reach downstream equipment, reducing downtime and maintenance costs.

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. Each option has its advantages, and selecting the right one is key to maximizing performance and cost-effectiveness.

Key Crossbelt Magnet Models and Their Applications

Bunting offers a variety of high-performance crossbelt magnets suited for different industrial needs. The OCW Heavy Duty Oil Cooled Electro Crossbelt Magnetic Separator is ideal for heavy-duty applications where maximum magnetic strength is required. It operates efficiently even at wider gaps and with heavier loads, making it perfect for deep troughed conveyors in recycling and mining operations.

The ACW Heavy Duty Air Cooled Crossbelt Magnetic Separator is another excellent option, especially when low maintenance is a priority. With an air-cooling system, it reduces the need for frequent servicing while still delivering strong magnetic performance. This model is well-suited for environments where oil cooling may not be practical.

For those requiring the highest level of power and flexibility, Bunting's Heavy-Duty Electro Crossbelt Magnetic Separators offer unmatched performance. These units are designed for deep material layers and can be installed inline over head pulleys or across the entire width of the conveyor belt, from 24” up to 78.5”. They are a top choice for large-scale mining and processing facilities.

How to Choose the Right Crossbelt Magnet for Your Operation

Selecting the appropriate crossbelt magnet involves evaluating several key factors. These include the primary goal of the separation—whether it’s protecting equipment, improving product purity, or enhancing safety. The characteristics of the tramp metal, such as size, shape, and magnetic properties, also play a crucial role in the decision-making process.

Additionally, the nature of the material being conveyed—its particle size, density, and flow rate—will influence the best magnet design for your setup. Bunting’s team of application engineers specializes in analyzing these variables and recommending the most suitable solution for each unique scenario.

With decades of experience and a commitment to innovation, Bunting continues to lead the way in providing reliable, high-performance magnetic separation solutions. Whether you're working in mining, aggregates, or recycling, we have the expertise and products to meet your needs.
