High-Intensity Magnetic Drum

       When material moves along a conveyor belt or roller into the magnetic separation zone, it enters the magnetic field of the high-intensity magnetic drum. Ferromagnetic contaminants such as iron powder, iron filings, and iron ore are attracted by the magnetic force and firmly adhere to the magnetized surface of the drum, while non-magnetic materials are discharged naturally under the action of gravity and centrifugal force and continue to be conveyed. As the drum rotates into a low-magnetism or demagnetized region, the adsorbed ferrous impurities are automatically released or removed, thereby achieving a continuous separation process. This technology is widely used in magnetic iron removal systems for iron powder.

Features and Advantages

• Localized High-Magnetism Design: A semi-magnetic structure (with localized high-magnetism zones) ensures precise separation and efficient ferrous contaminant removal.
• High Separation Efficiency: Suitable for the removal of fine ferrous impurities from ores, powders, and granular materials.
• High Magnetic Performance: Can be upgraded to configurations featuring strong magnetic drums, ultra-strong magnetic drums, or high-intensity magnetic drums.
• Wear Resistance and Durability: Designed for mining environments and industrial conveying systems, offering long service life and high operational stability.

Optional Configurations

• Customizable Designs: The equipment can be tailored in terms of structure and configuration to suit various ferrous contaminant removal scenarios, meeting the separation needs of powders, granules, and minerals.
• Adjustable Magnetic Field Strength: 1,500–3,000 gauss (for rough separation and low-iron-content applications); 3,000–6,000 gauss (for standard industrial separation); 6,000–8,000 gauss (for high-precision removal of ferrous impurities from fine powders).
• Optional Temperature Ratings: Available for ambient temperatures, as well as for 85°C, 100°C, 120°C, 150°C, and 350°C applications.
