Description

Technical Field

[0001] The utility model relates to a magnetic separator for selecting iron ore concentrate, belonging to the field of magnetic separation. Background Art

[0002] Magnetic separation is a process of separating different magnetic components in a material based on the magnetic differences of different components in the separated material. During the magnetic separation process, the mineral particles are subjected to multiple forces, including gravity, centrifugal force, water flow force and friction in addition to magnetic force. When the magnetic force on the magnetic mineral particles is greater than the sum of the other forces, they will be sucked out or deviated from the material flow and become magnetic products. The rest are non-magnetic products, thus achieving the separation of different magnetic minerals. Iron ore is processed into ore powder called iron concentrate through crushing, grinding, and beneficiation. If the ore powder is not screened during the feeding process, the ore powder with larger particles is easy to get stuck in the magnetic separator body, causing wear on the surface of the drum inside the magnetic separator body, which reduces the normal service life of the magnetic separator. Therefore, the present application proposes a screenable magnetic separator for selecting iron concentrate. Utility Model Content
