Magnetic Plates

What Is a Plate Magnet?

A plate magnet is a flat, permanent magnetic unit designed to remove tramp iron from bulk materials flowing through chutes, spouts, or on conveyor belts.

It works by generating a strong magnetic field that attracts and holds ferrous contaminants, bolts, screws, nails, and iron fragments, while clean material continues to flow.

Because plate magnets contain no moving parts and require no power, they are widely used as a first-stage protection device to prevent equipment damage, improve product purity, and reduce unplanned downtime in industrial processes.

The Working Principle of a suspended magnetic separator

A suspended magnetic separator works by creating a strong, permanent magnetic field across the surface of the plate, allowing you to capture ferrous contaminants as material passes by. Inside the housing, high-performance magnets are arranged in a focused magnetic circuit that pulls iron particles toward the plate and holds them securely.

When your material flows through a chute or moves along a conveyor, tramp iron such as bolts, screws, or iron fines is attracted to the magnetic field. Clean product continues downstream, while metal remains fixed to the plate surface. The closer the material is to the magnet, the stronger the separation effect you achieve.

Because the system uses permanent magnets, you don’t need power, control systems, or moving parts. This makes magnetic plates reliable, energy-free, and ideal for continuous operation. By choosing the right plate size, magnet strength, and installation position, you ensure stable and efficient metal separation in your process.

Application scenarios of plate magnets

Conveyor Belt System

Installed above the conveyor belt, used to continuously capture iron scraps, bolts, nuts, and other ferrous contaminants from the material, preventing them from entering crushers, mills, or screening equipment.

Chute & Hopper

Installed inside chutes or hoppers, utilizing the contact between the material and the magnetic plate as the material flows by gravity, efficiently removing iron impurities, especially suitable for powders and granular materials.

Discharge Point

Installed at the point where the material is discharged or dispersed, significantly increasing the probability of capturing iron impurities.

Mining, Building Materials, and Cement Industries

Used for iron removal from aggregates, sand, gravel, and cement raw materials, reducing equipment wear and ensuring continuous production.

Recycling and Solid Waste Treatment Industries

Effectively separates scrap iron mixed in the materials, improving recycling efficiency and protecting downstream equipment.

Grain, Feed, and Plastics Industries

Removes iron impurities from raw materials, improving product purity and reducing quality risks.
 

Our product packaging

GME provides safe, professional, and internationally compliant industrial-grade packaging for its magnetic plate separators, ensuring the products remain intact during long-distance sea transport and multiple loading and unloading processes.

Before shipment, your magnetic plate will undergo rust and scratch protection treatment, with key magnetic surfaces and edges reinforced with cushioning materials. The product is then secured in reinforced wooden crates or custom-designed steel structures to prevent displacement and vibration.

All packaging is clearly marked with the model number, weight, center of gravity, and lifting instructions, facilitating on-site receiving, handling, and installation. With GME, you receive not just equipment, but a reliable solution ready for immediate use.
