Low intensity Drum permanent magenetic separator
Description
A Low Intensity Drum Permanent Magnetic Separator is a widely used magnetic separation device designed to efficiently separate magnetic materials from non-magnetic materials in dry or wet processing environments. It utilizes permanent magnets, typically in the form of a drum, to create a low-intensity magnetic field that attracts ferromagnetic materials such as iron, steel, and other magnetic minerals. This type of separator is commonly employed in industries such as mining, coal processing, recycling, and waste management for the removal of tramp metal and the concentration of magnetic ores.

FUNCTION PRINCIPLE
Working Principle
The Low Intensity Drum Permanent Magnetic Separator works on the basic principle of magnetic attraction. It typically consists of a drum fitted with a series of permanent magnets. These magnets produce a magnetic field that attracts ferromagnetic materials as the drum rotates. The non-magnetic particles pass through the separator without being affected. Here’s how the process works:
- Feed Introduction:
- The material, usually in bulk or slurry form, is fed onto the rotating drum, which can either be dry or wet depending on the application. The material may consist of a mixture of magnetic and non-magnetic particles.
- Magnetic Field Generation:
- As the material flows over the rotating drum, the permanent magnets embedded within the drum create a low-intensity magnetic field. This magnetic field captures ferromagnetic materials and attracts them to the surface of the drum.
- Separation Process:
- The magnetic particles are pulled to the drum surface and held there due to the magnetic attraction. As the drum rotates, the material moves along the surface, and at certain points, the magnetic particles are discharged from the drum using a wiper or scraper mechanism into a separate collection bin.
- The non-magnetic particles pass through unaffected and are discharged through a different outlet.
- Drum Rotation:
- The drum rotates continuously, ensuring that the magnetic particles are constantly being attracted to and then discharged from the drum surface, providing a continuous process.
- Discharge of Magnetic and Non-Magnetic Materials:
- The magnetic fraction is collected from the drum, and the non-magnetic fraction continues to move along its path to be discarded or further processed.
