When choosing the ideal equipment to remove ferrous contaminants from industrial processes, a question often arises: choose a magnetic or electromagnetic separator? Despite having the same function — separating metallic particles —, these equipment have very different characteristics and applications. In this article, we explain the main differences to help you make the best decision.

What is a magnetic separator?

The traditional magnetic separator uses permanent magnets (such as neodymium or ferrite) to attract ferrous particles during the transportation or processing of materials. It is an efficient, low-cost and simple maintenance solution.

Main features:

• Does not consume electrical energy to generate the magnetic field
• Can operate continuously without overheating
• Ideal for dry, granular materials and environments that do not require constant removal of large volumes of metal

What is an electromagnetic separator?

The electromagnetic separator uses coils powered by electric current to generate a high-intensity magnetic field. Unlike a permanent magnet, it allows control over the magnetic force, which makes it more versatile in certain applications.

Main features:

• Adjustable magnetic field according to process needs
• Able to handle larger volumes of metallic material
• Requires electrical power and cooling system (in some cases)

Which is best for your industry?

The answer depends on the type of material processed and the amount of metallic contaminants. See some scenarios:

• Permanent magnetic separator is ideal for:
  • Food industries
  • Plastic recycling
  • Environments with low metallic contamination

• Electromagnetic separator is best suited for:
  • Heavy mining
  • Handling large volumes of ore
  • Industrial environments that require superior magnetic strength
