Rare Earth Magnetic Separator

1.Product Introduction Magnetic Separator

A Rare Earth Magnetic Separator is an industrial device that utilizes rare earth permanent magnetic materials (such as Neodymium Iron Boron, NdFeB) to generate a powerful magnetic field. It is designed to remove magnetic impurities from materials or to sort magnetic minerals. As a specialized type of high-intensity magnetic separator, it is widely utilized across various industries due to its high field strength, low energy consumption, compact structure, and ease of maintenance.

2.Application Magnetic Separator

Due to its high field strength and high-purity separation capabilities, this equipment is widely used in:

• Mining & Mineral Processing: Sorting weakly magnetic minerals like rare earth ores, ilmenite, zircon, garnet, and kaolin to improve concentrate grade.

• Food & Pharmaceuticals: Removing trace iron filings from raw materials (sugar, salt, milk powder, medicinal powders) to ensure safety and purity in compliance with GMP standards.

• Chemicals & New Materials: Purifying catalysts, phosphors, and lithium battery cathode materials (e.g., Lithium Cobalt Oxide) to prevent metal impurities from affecting performance.

• Resource Recycling: Recovering ferromagnetic metals from electronic waste, scrap tires, and waste plastics.

• Ceramics & Glass: Removing iron impurities from raw materials to prevent black spots after firing and enhance appearance.

3.Working Principle Magnetic Separator

The operation of the rare earth magnetic separator is based on magnetic susceptibility differentiation:

1. Feeding: Materials (dry powder, granules, or fluids) pass through the magnetic field zone of the equipment.

2. Capture: The rare earth permanent magnets arranged inside produce a high-gradient, high-intensity magnetic field.

3. Adsorption: Ferromagnetic substances (such as iron, cobalt, nickel) and some paramagnetic substances (such as certain rare earth minerals or ilmenite) are attracted and adsorbed onto the surface of magnetic rollers, grids, or drums.

4. Separation: Non-magnetic materials remain unaffected and continue along their original path, achieving separation.

5. Discharge: The adsorbed magnetic particles move with the magnet to a non-magnetic zone, where they are removed by scrapers, rinsing, or gravity, allowing for continuous operation.

4.Advantages Magnetic Separator

• Extreme Magnetic Strength: NdFeB magnets can generate fields up to 15,000–20,000 Gauss, effectively sorting weakly magnetic substances that traditional equipment cannot handle.

• Low Energy & No Overheating: As a permanent magnet system, it requires no electricity for excitation, leading to lower operating costs and no heat-related safety risks from coils.

• Compact & Easy Maintenance: Without complex coils or cooling systems, the equipment is small, flexible to install, and requires minimal daily maintenance.

• High Separation Precision: The high-gradient design enables the capture of micron-sized impurities, achieving product purity levels of over 99%.

• Eco-friendly & Sustainable: Zero electromagnetic pollution aligns with green manufacturing trends; furthermore, rare earth magnets have a long service life, offering excellent long-term economy.
