Four tips for cement vertical roller mill maintenance


First of all, production maintenance mainly refers to the elimination of production planning problems, the production can not keep up, the finished products are not up to standard, etc. There are two possible failure factors: one is the performance of the equipment itself, the other is the level of the operator, the general test machine does not There are quality problems, and the factors affecting the quality of the grinding equipment in the later stage are much smaller, which may not be caused by the operator. For example, the uniform feeding cannot be controlled, the order of starting and shutting down is incorrect, and the opening status of each valve is incorrect. For example, the lock of the locker is not Jiahui will produce less or no powder, and the yield will be low. The uneven feeding will affect the uniformity of the finished product and the problem of blockage has occurred.
Second, predictive maintenance, similar to preventive maintenance, but there are essential differences, prevention is all possible problems, but the substance does not necessarily occur, and the prediction has already occurred, has been predicted to varying degrees, but has not yet Causes serious consequences. Predictively, according to the information provided by the state monitoring and diagnostic technology, necessary and appropriate maintenance can be carried out before the failure occurs. Most skilled operators can find potential faults in advance through sound and finished product status, so as to prevent and control early.
Third, preventive maintenance, develop detailed plans for the operation of vertical roller mill, including production volume, schedule, professional maintenance department, etc. Reasonable work arrangements and preventive measures can extend the service life of equipment and accessories and improve production efficiency. The following points:
1. Develop a reasonable production plan to avoid overworked equipment.
2. Set up a special maintenance department to check regularly and find out that the abnormal quality of finished products and production efficiency are eliminated in time.
3. Lubricate or replace the minor or severe wear parts of the vertical roller mill.
Fourth, fault repair refers to the unplanned maintenance taken when the cement vertical roller mill fails or the performance is degraded. It is more specific to the fault phenomenon. For example, the powder collector does not produce powder, the bearing is locked, and the Dust abnormalities in the material port, etc., such common faults. The Shibang Industrial Technology Group mine has introduced the detailed technical description of the milling equipment. In addition, the fault problem cannot be handled at will. Look for the technician or check and eliminate it under the knowledge of the technician. The entire process of failure should be carried out under power-off conditions to avoid other accidents.
