[0002] Wet magnetic separator is commonly used iron ore equipment and manganese ore equipment, and it is mainstream strong magnetic separator beneficiation equipment. Wet permanent magnetic cylinder magnetic separator is mainly composed of cylinder, roller, brush roll, magnetic system, groove body and transmission part. Cylinder and end cover are connected by screw. Under the action of magnetic field, magnetic particles form "magnetic group" or "magnetic chain" by magnetic aggregation. They are adsorbed on the cylinder due to magnetic force. Since the polarity of magnetic pole is alternately arranged along the rotation direction of cylinder and fixed during work, "magnetic group" or "magnetic chain" produces magnetic stirring phenomenon when rotating with cylinder. Gangue and other non-magnetic minerals mixed in "magnetic group" or "magnetic chain" fall off during stirring. Finally, "magnetic group" or "magnetic chain" on the surface of cylinder, i.e. concentrate, is adsorbed. When magnetic separator roller is used, cylinder and end cover are fixedly connected by screw. The sealing protection of roller is not good. Water in ore pulp can easily penetrate into the interior of cylinder, which can easily affect the normal use of magnetic system in cylinder.
