Fixed sorting electromagnet (RD)

In brief

• The fixed sorting electromagnet (RD) is installed above a conveyor and extracts unwanted ferromagnetic particles from a material flow.
• It is used in mining and quarrying, recycling, cement plants, foundries, food processing and the chemical industry.
• It has an anodised aluminium coil embedded in epoxy resin, 4 suspension lugs and a 110 V or 220 V DC power supply.

Applications

The fixed sorting electromagnet is used in

several sectors:

• Mining and quarrying
• Recycling and waste treatment industry
• Cement plants and foundries
• Food processing and chemical industry

Operating principles

Operating principle of our fixed sorting electromagnets**:**

• The fixed sorting electromagnet is designed to capture and extract unwanted ferromagnetic particles present in a material flow.
• Installed above a conveyor, it generates a strong magnetic field that attracts and retains metal contaminants.
• Once separation is complete, de-energising the electromagnet releases the recovered metal particles.

Operating recommendations

Recommendations from our Lenoir-Mec experts:

• Optimal positioning: Install the magnet at a suitable height for maximum efficiency according to the particle size of the product.
• Regular cleaning: De-energise the magnet and manually remove the accumulated metal particles.
• Checking the fastenings: Regularly inspect the condition of the suspension chains and supports to ensure stability.
• Thermal monitoring: Use a temperature probe to prevent any overheating of the electromagnetic system.
• Combination with a metal detector: To improve selectivity and limit energy consumption.

Frequently asked questions

How does the RD fixed sorting electromagnet work?

Installed above a conveyor, it generates a strong magnetic field that attracts and retains ferromagnetic contaminants. De-energising the electromagnet then releases the recovered particles.

What materials is the RD electromagnet made of?

It has a magnetic circuit in high-permeability steel and an anodised aluminium coil embedded in epoxy resin for greater durability. The suspension is secured by 4 robust fixing lugs.

What power supply does the RD electromagnet require?

It is available with a 110 V or 220 V DC power supply. A permanent magnet version (APRF) is also available.

How should the RD electromagnet be cleaned and monitored?

To clean it, de-energise the magnet and manually remove the accumulated metal particles. A temperature probe prevents any overheating, and the condition of the suspension chains and supports must be checked regularly.

In which sectors is the fixed sorting electromagnet used?

It is used in mining and quarrying, recycling and waste treatment, cement plants and foundries, food processing and the chemical industry. Combining it with a metal detector improves selectivity and limits energy consumption.
