Description

Technical Field

[0001] The utility model relates to the technical field of various mixed ore separation processes, in particular to a self-testing concentration and self-adjusting magnetic force separator. Background Art

[0002] At present, most of the magnetic separators used by our company are fixed magnetic separators. Magnetic separators are screening equipment used to extract magnetic substances from the medium. The equipment can use the magnetic difference of the separated materials to separate minerals. Magnetic separators include dry magnetic separators and wet magnetic separators. Dry magnetic separators are widely used due to their small footprint, simple process, water conservation, and no ore dressing wastewater discharge. There are certain limitations in use; with the development of magnetic separators, accelerating material separation through flowing water has become a sorting method, but when this sorting method is used for magnetic separation, due to the fixed magnetic force between the material particles, the magnetic and non-magnetic materials in the material will be insufficient due to the magnetic force of the equipment, resulting in the phenomenon that the magnetic materials cannot be fully separated. In order to fully extract, we now use multiple magnetic separator processes for magnetic separation, which is not only slow, but also has the defects of poor sorting accuracy. Therefore, a self-testing concentration and self-adjusting magnetic separator is urgently needed to solve the above problems. Utility Model Content
