Problems solved by technology

However, most electromagnetic magnetic separators are limited by their separation principles and structures, and the particle size of the selected materials can only be below 0.5mm. Although the electromagnetic induction roller strong magnetic separator can be used for wet separation, its selected The particle size can only be below 2mm. At the same time, the induction roller wears quickly during production, and the wear of the induction roller will cause the decline of

Example Embodiment

[0014] Adjust the position of the permanent magnet as shown in Figure 1; adjust the position of the adjustment plate on the overflow of the sorting tank to ensure a high sorting liquid level; make the sorting cylinder rotate in the opposite direction relative to the material; the material is at an angle of 0~45 with the horizontal The degree direction is given to the surface of the sorting cylinder immersed in the water; as the sorting cylinder rotates, the non-magnetic minerals are not affected by the magnetic field and naturally settle in the water, enter the tailings bucket, and act as tailings. The mine mouth is discharged; magnetic minerals are affected by the magnetic field force of the magnet in the cylinder, and are adsorbed on the surface of the sorting cylinder and rotate together with the sorting cylinder. At the same time, the rinsing water on the upper part of the sorting cylinder is magnetic to the surface of the sorting cylinder. The minerals are constantly washed t...

Abstract

The present invention relates to method and apparatus for separating fine material. The apparatus has one rotating cylinder, one feeding bin in the upper part of the cylinder, one permanent magnet to generate one non-uniform magnetic field in the upper part of the cylinder, one mineral unloading plate in the concentrate area, and one damping sheet to separate mineral in the interface between the concentrate area and the tailing area. The present invention has the advantages of different types of magnetic separator combined together, has great mineral output and capacity of separating concentrate and tailing, and is especially suitable for separating material in the granularity up to 8 mm.

Description

technical field [0001] The invention relates to a method and equipment for beneficiation, in particular to a method and equipment for sorting fine-grained materials. Background technique [0002] Electromagnetic and A permanent magnet magnetic separator is used for sorting. Since the primary ore of fine-grained minerals itself contains a certain amount of water, it is easier to bond into agglomerates after being crushed. At this time, the viscosity formed by water between the materials is much greater than the magnetic force, so the fine-grained materials are wet Sorting is a good sorting method. However, most electromagnetic magnetic separators are limited by their separation principles and structures, and the particle size of the selected materials can only be below 0.5mm. Although the electromagnetic induction roller strong magnetic separator can be used for wet separation, its selected The particle size can only be below 2mm. At the same time, the induction roller wea...
