Drum Type Magnetic Separator – PBS with Nd-Fe-B Permanent Magnet System
DEVICE:
The Turkenich roller magnetic separator with strong Nd-Fe-B magnets consists of one drum magnetic separator and one or more magnetic rollers located below it. The drum separator is designed to remove grains with increased magnetic susceptibility from the source power. Magnetic induction on its surface 0.36 T. Magnetic rollers consist of alternating magnetic and iron disks with a diameter of 92 mm. Induction on the surface of the rollers 1.8 – 1.9 T. On rollers, weakly magnetic grains are removed from the enriched material. The separator with a magnetic roller length of 1m has a modular design.

CONSTRUCTION FEATURES:
The enriched material is fed to the open surface of the roller. The separation is carried out directly on the surface of the roller, where the magnetic field reaches 1.9 T, which is more than in the separation zone of any magnetic or electromagnetic separator. The material to be enriched is tested for enrichment in a small laboratory roller separator. It can also be used in industry with a capacity of up to 1 t / h.
ADVANTAGES OF USE:
- The maximum possible degree of purification of materials from weakly magnetic inclusions;
- In the separator there is no tape at all, which is used in all roller separators to remove the magnetic product from the roller;
- Due to the absence of tape, the separator has high induction in the separation zone, is structurally simple and reliable in operation, has low operating costs.
APPLICATION EXAMPLE: CLEANING QUARTZ SAND FOR THE GLASS INDUSTRY.
The initial raw material was molding quartz sand of the Volnogorsk Mining and Metallurgical Combine.
- Sand size: 0.315-0.063.
- Content of Fe 2 O 3 ,% in nutrition: 0.05-0.25
- Content of Fe 2 O 3 ,% in purified sand: 0.020-0.030
- Non-magnetic product yield,%: 98-99
- The results obtained comply with the requirements for sand grades: BC-030-B and BC-020-B.
EXAMPLE OF APPLICATION: SUPER-DEEP CLEANING OF QUARTZ SAND.
The content of Fe 2 O 3 in the sand is 700 ppm. The content of Fe 2 O 3 in the purified sand after two separation methods is 12 – 16 ppm.
