Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical mine beneficiation equipment, and more specifically, to an adjustable device for the concentrate recovery of a dry magnetic separator. Background Art

[0002] In the roller grinding process of the ore plant, the closed-circuit crushing - pre-tailing discarding process of a high-pressure roller mill is adopted. After the discharged products of the high-pressure roller mill are screened by a linear screen, the materials with a particle size of more than +5mm are separated by two CTX0816 dry magnetic separators. The concentrate is returned to the closed-circuit crushing of the cylindrical bin, and the tailings are sold as comprehensively utilized products.

[0003] By sampling, it is found that the grade of the dry-discarded tailings continues to be high, and the grade of magnetic iron in the chemical analysis also increases significantly. Due to the increase in the content of fine powder in the raw ore and the serious slime phenomenon, after wet screening, some fine-grained minerals are adsorbed on the surface of the lumpy ore. This part of the material has a large viscosity, resulting in serious blockage of the material between the partition plate at the discharge hopper of the dry-discarding belt and the magnetic roller gap. In production, the concentrate cannot be completely recovered, and some of the concentrate enters the tailings, causing waste of iron resources.

[0004] Therefore, we make improvements and propose an adjustable device for the concentrate recovery of a dry magnetic separator. Content of the Utility Model
