Mills Machines Maintenance

Maintenance of mill machines (such as SAG, Ball, and Rod mills) is one of the most critical aspects of mining operations because mills are central to ore processing. Here’s a structured overview:

 

Core Maintenance Practices

Preventive Maintenance: Scheduled inspections of liners, bearings, gears, and lubrication systems.

Regular replacement of wear parts before failure.

Predictive Maintenance: Condition monitoring using vibration analysis, oil sampling, and thermography.

Laser scanning of mill interiors to track liner wear and forecast reline schedules.

Corrective Maintenance: Onsite repairs of cracks, welding, and refurbishments.

Gear and pinion alignment corrections.

Shutdown Maintenance: Planned shutdowns for relining, shell inspections, and major overhauls.

Coordinated with production schedules to minimize downtime.

 

Benefits of Proper Maintenance

Extended Equipment Life: Regular monitoring prevents catastrophic failures.

Reduced Downtime: Predictive tools allow maintenance to be scheduled at optimal times.

Improved Efficiency: Well-maintained liners and lifters improve grinding performance.

Cost Control: Preventive strategies reduce emergency repair costs.

Safety: Less manual inspection inside mills reduces operator risk.
