Lubrication helps reduce friction and wear between moving parts, supports stable machine operation, and can extend the service life of stone processing equipment. Poor lubrication may lead to overheating, abnormal noise, premature component wear, or unexpected downtime.

 

Operators are responsible for checking lubrication conditions, following the equipment's lubrication schedule, and keeping lubrication components in good condition. The following requirements provide a practical starting point for daily maintenance.

 

 

Before starting the equipment, carefully check the oil supply and confirm that the lubrication system is working as required.

 

If an oil supply fault, abnormal oil level, leakage, or other problem is found, report it to the responsible supervisor immediately. Qualified maintenance personnel must inspect and repair the fault before the machine is operated.

 

Do not start the equipment while a lubrication fault remains unresolved.

 

 

Lubricate each designated point according to the machine's lubrication chart and maintenance schedule. Stone machinery lubrication should follow the five-fixed-principle system:

 

- Fixed personnel: Assign clear responsibility for lubrication work.

- Fixed time: Lubricate at the specified intervals.

- Fixed quality: Use the specified lubricant grade and type.

- Fixed quantity: Apply the required amount of lubricant.

- Fixed points: Lubricate the designated points on the machine.

 

Following these requirements helps prevent missed lubrication points, incorrect lubricant selection, and over- or under-lubrication.

 

Always refer to the equipment manufacturer's instructions for lubricant specifications and service intervals.

 

 

Clean lubrication-related components at the intervals specified by the maintenance plan. These may include oil wicks, oil lines, oil holes, oil-level indicators, and oil filters.

 

Dirt, sludge, or blockages can interfere with lubricant delivery. Regular inspection and cleaning help keep the lubrication system functioning properly.

 

Replace damaged or clogged components when necessary, following the manufacturer's maintenance instructions.

 

 

Inspect and maintain lubrication devices such as oil cups, grease nipples, and other lubricant delivery components.

 

Check for damage, looseness, leakage, or blockage. Make sure each device can deliver lubricant to its intended location and that covers or seals are correctly fitted where required.

 

If a lubrication device is damaged or cannot function normally, arrange for repair or replacement before the problem causes further wear.

 

 

Before or during scheduled maintenance, operators can use this checklist to help keep stone processing equipment in good working condition.

 

-  Check the oil supply and inspect for leaks or abnormal conditions.

-  Confirm that the lubrication system has no unresolved faults.

-  Lubricate all designated points according to the equipment chart.

-  Use the specified lubricant and required quantity.

-  Clean oil lines, oil holes, filters, and other components as scheduled.

-  Inspect oil cups, grease nipples, and related lubrication devices.

-  Report faults and record maintenance work according to the site's procedures.

 

Safety reminder: Follow the machine's shutdown and isolation procedures before cleaning, servicing, or repairing lubrication components. Never reach into moving machinery to inspect or maintain the lubrication system.

 

 

Effective lubrication depends on consistent inspections, correct lubricant selection, scheduled maintenance, and clear responsibility among operators and maintenance personnel. By following the equipment's lubrication chart and addressing faults promptly, stone processing plants can reduce avoidable wear and keep machinery operating more reliably.
