Abstract

The invention relates to the field of performance study of magnetic separators, and discloses a method for solving the problem of mix inclusion of a magnetic separator. A magnetic roller of the magnetic separator is sprayed and coated with a layer of composite magnetic material, the composite magnetic material is prepared from the following components including, by weight, 30-35 parts of ultra-fine iron oxide powder, 15-20 parts of silicon carbide nanometer micro powder, 10-13 parts of titanium dioxide, 8-10 parts of calcium oxide, 7-9 parts of manganese oxide, 4-6 parts of yttrium oxide and 2-4 parts of cerium oxide; the prepared ultra-fine iron oxide powder is even in particle, the obvious volume effect and surface effect are achieved, superpara magnetism conversion happens, and under the action of a magnetic field, the very high mobility is achieved; and the calcium oxide, the manganese oxide and rare earth oxide serve as stabilizers, and therefore magnetism can be strengthened, influences of outside environment changes are avoided, the prepared Ti3SiC2 powder has the high temperature resistance, high oxidation resistance and the other characters, and the service life of a coating is prolonged.

Description

Technical field [0001] The invention belongs to the technical field of performance research of magnetic separators, and specifically relates to a method for solving the mixed inclusion problem of magnetic separators. Background technique [0002] Magnetic separators are used to remove iron powder from powdered granules. Magnetic separators are widely used in resource recovery, wood industry, mining, ceramics, chemical, food and other factories, suitable for magnetic particles with a particle size of 3mm or less. Wet magnetic separation of iron ore, pyrrhotite, roasted ore, ilmenite and other materials is also used in the removal of iron from coal, non-metallic ore, building materials and other materials. It is the most widely used and highly versatile in the industry One of the models. In the magnetic field of the magnetic separator, the magnetic particles are not only affected by magnetic force but also by competitiveness. Competitiveness can be defined as the resultant force ...
