Description

Technical Field

[0002] Magnetic separator is one of the most widely used and versatile machines in the industry. It is suitable for separating materials with different magnetic properties. Magnetic separator is widely used in mining, wood, kiln, chemical, food and other industries. After the material flows into the tank, the magnetic ore particles are magnetically gathered under the action of the magnetic field to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the cylinder rotates. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic chains" adsorbed on the surface of the cylinder are the concentrates. With the use of magnetic separators, more and more magnetic substances accumulate on the surface of the drum, and the cleaning mechanism of the magnetic separator becomes extremely important.
