China Arc Magnet Manufacturer, Supplier, Factory

Arc Magnet is a sophisticated and highly efficient magnetic separation system engineered for industrial applications where purity and process efficiency are paramount. Designed to meet the rigorous demands of sectors such as mining, recycling, food processing, and chemical manufacturing, this system leverages advanced magnetic circuit technology to extract ferrous contaminants with exceptional precision.

Core Technology and Working Principle

The Arc Magnet system employs a high-intensity, permanent magnetic arc. This unique curved design creates a deep magnetic field across its entire surface. As material flows over or under the arc (depending on the configuration), ferrous metals are powerfully attracted and held securely against the magnetic face. Non-magnetic material continues its trajectory unaffected, ensuring a clean separation. The system is typically self-cleaning; a motor-driven belt or a manually operated slide mechanism removes captured tramp metal, allowing for continuous operation without downtime.

Arc Magnet FAQ: Common Questions Answered

What is the main advantage of an Arc Magnet over a standard plate magnet?

The primary advantage is the depth and shape of the magnetic field. The curved arc design provides a much deeper magnetic reach compared to a flat plate. This allows it to capture ferrous contaminants from thicker material beds or from a greater distance within a falling stream, making it significantly more effective for high-volume or high-flow-rate applications.

How do I choose between a Rare-Earth and a Ceramic Ferrite magnet version?

The choice depends on the type of contamination and the required magnetic strength. Rare-Earth (NdFeB) Arc Magnets deliver the highest intensity, ideal for removing fine, weakly magnetic particles (like work-hardened stainless steel) or when processing material at high speeds or in deep layers. Ceramic Ferrite models offer a robust and cost-effective solution for removing larger tramp iron (nuts, bolts, nails) from standard material flows.

Does the Arc Magnet require electricity to operate?

The magnetic core itself, being permanent, requires no electrical power. This makes it energy-efficient and safe for use in explosive atmospheres (with appropriate certification). However, the optional self-cleaning mechanism, which uses a motor-driven belt, does require a standard electrical connection.

What maintenance is typically required for an Arc Magnet separator?

Maintenance is minimal. For self-cleaning models, routine checks include inspecting the belt for wear, ensuring the drive motor and bearings are lubricated according to schedule, and verifying belt tension. The magnetic arc itself requires no maintenance. It is also crucial to periodically check that the surface of the magnet is clean and free from any material buildup that could hinder performance.

Can the Arc Magnet handle hot materials?

Yes, but with specific configurations. Standard rare-earth magnets lose strength at high temperatures. We offer high-temperature versions with specially stabilized magnets and heat-resistant designs for processing materials up to 180°C (356°F). It is essential to specify your maximum operating temperature during the selection process.

Is the system suitable for food-grade applications?

Absolutely. We offer sanitary Arc Magnet models constructed with 316 stainless steel, fully sealed and polished to a high microbial finish. These units use FDA-approved white belts and are designed for easy integration into HACCP and hygienic processing lines, allowing for frequent wash-downs without risk of corrosion or contamination.

How do I determine the correct model size for my conveyor or chute?

The key dimensions are the width of your conveyor belt or the width of the material stream in your chute. The Arc Magnet should be at least as wide as the belt or stream. Our engineers use additional factors like material depth, flow rate, density, and the size of contaminants to recommend the optimal model and magnetic strength. We provide detailed sizing guides and application support to ensure correct selection.

What happens if a very large or heavy piece of tramp iron is captured?

The Arc Magnet is designed with significant holding force. However, for applications with a risk of extremely large or heavy ferrous objects, we recommend an initial stage of protection, such as a magnetic grate or a drum separator, to remove bulk metal. The Arc Magnet then acts as a fine or finishing separator. The self-cleaning mechanism is also engineered to handle a designed load capacity.
