Many mines will carry on to experience decreased profit margins, to some extent because their maintenance team does not really fully understand the maintenance requirements of the rock crushers that they are liable for.

Listed below are a few completely different types of crusher maintenance that must be thoroughly understood regardless of the crusher sort being used.


Implementing a preventative maintenance program is the best method of keeping a crusher in good operating condition for a long time period. Preventive maintenance will include scheduled inspections, inspections and services at typical time intervals as recommended by the rock crusher manufacturer.

Preventive maintenance is typically set up on a daily (8 hours), each week (40 several hours), monthly (200 hours), yearly (2,000 hours), and liner change schedule. Following the slated checks and home inspections, adjustments are made and put on parts are replaced just before a major crusher breakdown occurs. Preventive maintenance is a key element in maximizing the crusher’s life period.


Refers to checking the condition of the rock crusher while it is in procedure. This is completed by utilizing predictive maintenance tools available such as however, not limited to, lubricating oil temperatures sensors or even thermometers, lubricating oil pressure devices or indicators, lubricating oil tank come back screen, lubricating oil filtration condition indicator, crusher coast down time, no-load head spin, lube oil analysis reports, crusher drive motor power draw readings, vibration indicator readings and completed daily operator crusher log sheets.

These kinds of predictive maintenance tools can be used to help learn and comprehend the rock crusher’s normal running condition or characteristics. Once the typical operating condition or perhaps characteristics continues to be determined, virtually any data collected that appears to be abnormal compared to the regular would show a crusher problem and justify a closer investigation.

At this point, parts can end up being ordered and effort can be scheduled well before the crusher encounters a failure. Creating a crusher repair based on a great abnormal running condition will always be considered cost effective.


Right here preventive and predictive maintenance is overlooked and the crusher is allowed to function, with no action taken to correct an unusual condition, until the crusher really experiences failing. This run-to-failure frame of mind reaps short term financial savings for the mine but results in massive crusher repair expenses and interruptions in production because a small problem will eventually snowball in to a catastrophic crusher disappointment.
