Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of magnetic separators, in particular to a drum magnetic separator. BACKGROUND
[0002] The magnetic separator is used for removing iron powder in the recycling of powdery particles. After the ore pulp flows into the tank through the ore feeding box, the ore particles enter the ore feeding area of the tank in a loose state under the action of the water flow of the ore feeding water pipe. Under the action of the magnetic field, the magnetic ore particles form "magnetic groups" or "magnetic chains" through magnetic aggregation. The "magnetic groups" or "magnetic chains" move towards the magnetic pole under the action of the magnetic force in the ore pulp and are adsorbed on the cylinder.
[0003] However, in the actual process, a large amount of magnetic powder is adsorbed on the outside of the cylinder. As the cylinder rotates with the magnetic groups towards the area without a magnetic field, the magnetic groups can fall into the discharge box. However, at the edge of the magnetic field, the magnetic groups continue to gather around it, which causes the magnetic groups to be unable to quickly fall into the discharge box. To some extent, the magnetic groups adhere to the outside of the cylinder. Therefore, the drum magnetic separator is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
