As the main crushing equipment, crusher is widely used in mining, sand and gravel enterprises, solid waste disposal and other fields. Common crushers include jaw crushers, cone crushers, impact crushers, hammer crushers, impact crushers, etc. These crushers all contain very important power systems, with bearings, rotors, rotating shafts, etc. as rotation The internal components in the device can not be underestimated for the smooth operation of the crusher. The rotating shaft rotates with the bearing as the support. Both friction and wear are relatively large. Failure of the bearing, rotating shaft, rotor and other components to shut down and repair will inevitably affect the working conditions, extend the production cycle, and increase the investment cost of the enterprise.

Method for detecting failure of rotating device of crusher

Take for example the bearing failure, the rotation shaft failure and the rotor (fixed or dynamic) failure in the crusher's rotating device. When the crusher is working, once the bones, rustling or discontinuous abnormal sounds are heard, it is most likely that the crusher bearing has failed. At this time, one by one should check the oil content of the rolling bearing, whether there is wear and rust in the bearing , The method to check whether the bearing is worn is to hold the outer ring while pinching the outer ring and push it in all directions. If it can be easily pushed, it means that the wear is serious; the failure of the rotating shaft generally shows the deformation of the rotating shaft and the bending of the shaft; Abnormal failure, mainly check the internal iron core.

countermeasures for the failure of the crusher rotating device

When the bearing of the crusher breaks down, it should promptly and correctly add oil to the rolling bearing, and optionally use sandpaper to wipe off the bearing rust and other methods to clean up the internal impurities or replace the damaged bearing to maintain the cleanliness and effectiveness of the rotating device. When the rotating shaft is completely deformed, the rotating shaft cannot continue to rotate normally. We need to analyze it in two cases. If the bending degree of the rotating shaft is small, you can use slip rings and other methods to repair and correct the board. A new shaft must be replaced, otherwise the crusher will have a more serious shaft failure. After the inner core of the rotor is damaged, it should be analyzed for any reason caused by moisture or poor assembly, and then the corresponding grinding or replacement measures should be carried out.
