The key factors for changing the lubricating oil on your ore sand making machine are the bearing lubrication method and the operating environment. Let me explain:
Bearing Lubrication Methods and Cycles
Grease Lubrication (Most Common):
Regular Replacement: Add grease every 400-500 hours of operation; clean the bearings after 2000 hours of operation; replace the bearings after 7200 hours.
Special Environments: In high-temperature (e.g., 100℃), dusty, or humid environments, shorten the replacement cycle to every 3-6 months or change the oil depending on its condition.
Oil Lubrication (Oil Bath/Circulating Lubrication):
Oil Bath Lubrication: When the temperature is ≤50℃ and the environment is clean, change the oil approximately once a year; when the temperature reaches 100℃ or under harsh conditions, change the oil every 3 months.
Circulating/Jet Lubrication: Replacement intervals depend on oil circulation speed and cooling effect, and must be determined through testing and regular inspections.
Key Influencing Factors
Operating Environment: High temperature, high humidity, and dusty environments accelerate oil deterioration, requiring shorter replacement intervals.
Oil Condition: Replace immediately if the oil becomes darker, contains moisture or metallic impurities, or hardens.
