Disc Separators

Disc Separators are widely used to ensure an accurate separation of materials that have varied magnetic susceptabilities.

The Disc Separator has a very lengthy history, with its original designs dating back to the early 1900s. Although manufacturing techniques have significantly changed and more advanced machines have now been incorporated, the basic design still remains virtually the same.

Product Description

Disc Separators are widely used to ensure an accurate separation of materials that have varied magnetic susceptabilities.

The Disc Separator has a very lengthy history, with its original designs dating back to the early 1900s. Although manufacturing techniques have significantly changed and more advanced machines have now been incorporated, the basic design still remains virtually the same.

Typically, a Disc Separator will feature up to three high-intensity electromagnetic discs, each set at a different height from a feed conveyor. The first disc will be set the furthest from the feed material, in order to extract only the most magnetically susceptible particles. The second and third discs are set at lower gaps, increasing the magnetic force at each disc and therefore separating different grades of magnetic material. Magnetic intensity can also be further adjusted by varying the current of each coil to suit each clients specific mineral separation requirements.

Operation

Feed material is discharged from a hopper onto a Vibratory Feeder tray. A thin layer of material is continuously fed between the rotating high-intensity magnetic discs, where magnetic particles are attracted to the high-gradient zones on the discs. These captured particles are then carried by the rotating discs to the discharge chutes where they are released. Scrapers that are mounted on each of the chutes ensure the total discharge of the extracted magnetic particles. Any feed material that is non-magnetic will pass under each of the three discs and discharge at the end of the conveyor.

Applications

Typical applications for the Disc Separator include: • Concentration of dry, granular minerals such as ilmenite, garnet, monazite, wolframite, columbite-tantalite, etc. • Removal of minerals of low magnetic susceptibility from cassiterite, zircon, scheelite, rutile, etc. • Purification of quartz for glass manufacturing • Purification of abrasives • Extraction of iron oxides from chemical and food products. • The removal of feebly magnetic particles from swarf.
