Causes of several common failures of magnetic separators
Classified according to the strength of the magnetic field, magnetic separators can be divided into weak magnetic field magnetic separators, medium magnetic field magnetic separators, and strong magnetic field magnetic separators. At present, the wet drum magnetic separator is the most widely used, and the wearing parts include drum skin, magnetic block, groove bottom, transmission gear, etc.
The main reasons for the failure are that large-volume debris enters the magnetic separator, the magnetic block falls off, the performance of the magnetic block is degraded, and the lubrication effect is not good.
1. The bulky debris enters the magnetic separator. Large-volume debris enters the magnetic separator, which may scratch the cylinder skin in light cases, or jam the cylinder in heavy cases, causing the equipment to stop; in addition, there may also be holes in the tank body, resulting in ore leakage in the tank body.
2. The magnets come off. When the magnetic block in the drum of the magnetic separator falls off seriously, the shell of the drum will be scratched, and it needs to be stopped immediately for maintenance.
3. Magnetic block performance degradation. If the service life of the magnetic separator is too long, the performance of the magnetic block will be degraded, and the strength of the magnetic field will be reduced, which will affect the sorting effect.
4. The lubrication effect is not good. Poor lubrication can lead to problems such as wear and tear of the transmission gear.
