Manufacturers of grinding mills suggest regular and proactive scheduled maintenance practice to ensure longevity and performance of the machine. “Regular checks will prevent equipment failure” says air classifier manufacturers in India. Preventive maintenance services of the manufacturing unit are intended to enhance reliability and availability. There are many benefits of regular inspection and maintenance practice-
- Extended equipment life
- Lower downtime
- Lower operations and maintenance costs
- Enhanced process performance
- Support maintenance program
All the tasks are performed by specialists who understand the functions and features of the system and have knowledge about using them. Experienced mill specialists carry out the maintenance inspection on site. The two-day inspection is categorized in two phases. In the first phase, the mill is operating in normal condition and at normal load. Specialists use advanced analyzers and instruments for the inspection. Components checked in the first phase-
- Trunnion bearings
- Pinion bearings
- Ring gear
- Pinion gear
- Electric motor
- Bearing lubrication systems
- Pinion-ring gear grease system
In the second phase, mill is continuously running without feed until most of the material and water has passed through. Specialists look at these components in second phase-
- Mill pinion gear
- Mill pinion bearings
- Mill ring gear
- Trunnion bearing
- Gearbox and inching drive
- Mill foundation
- Coupling alignment
- Feed elbow
- Discharge trammel
- Mill linings shell, feed, and discharge heads
Later, evaluation process is done by experts. The condition and needed action is evaluated for each procedure. Experts evaluate the maintenance status of the equipment and provide feedback and recommendations to the users.
What happens when users take their grinders for granted?
When any person neglects the grinding mill maintenance and ignores the faults, he needs to pay higher repairing costs. Regular maintenance practice keeps all risks of failure away and protects the system and enhances longevity. But when one ignores the need of maintenance and continues to use grinding mil, it put bad impact on internal components and makes them wear at faster rate.
Air classifier manufacturers suggest regular checks and tests should be done for grinding mill machine to protect internal components against premature wear and tear.
