HOW DOES A JAW CRUSHER WORK?


Many mines will continue to experience reduced profit margins, partly because their maintenance team does not necessarily fully understand the maintenance requirements of the rock crushers that they are responsible for.

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






Preventive

Implementing a preventive maintenance program is the best method of keeping a crusher in great operating condition for a long period of time. Preventive maintenance will contain scheduled checks, inspections and services at regular time intervals since recommended by the rock crusher producer.

Preventive maintenance is generally set up on a daily (8 hours), each week (40 hrs), monthly (2 hundred hours), yearly (2,000 hrs), and liner change timetable. Following the planned checks and inspections, adjustments are made and used parts are replaced before a major crusher breakdown takes place. Preventive maintenance is a key component in maximizing the crusher’s life period.

Predictive

Refers to checking the condition of the rock crusher while it is in operation. This is achieved by utilizing predictive maintenance tools obtainable such as but not limited to, lubricating oil temperatures sensors or perhaps thermometers, lubricating oil pressure sensors or assessments, lubricating oil tank return screen, lubricating oil filtration system condition indicator, crusher coast down time, no-load head spin, lube oil analysis reviews, crusher drive motor power draw readings, vibration indicator readings and completed daily owner crusher log sheets.

These kinds of predictive maintenance tools can be used to help learn and understand the rock crusher’s normal running condition or characteristics. Once the regular operating condition or even characteristics has been determined, any data collected seems to be abnormal compared to the normal would show a crusher problem and bring about a closer analysis.

At this point, parts can be ordered and workforce can be planned well before the crusher encounters a failure. Creating a crusher repair based on a good abnormal working condition will always be considered cost effective.





Reactive

The following preventive and predictive maintenance is overlooked and the crusher is allowed to run, with no action taken to appropriate an abnormal condition, until the crusher really experiences failing. This run-to-failure frame of mind reaps short term cost savings for the mine yet results in massive crusher repair costs and interruptions in production since a small problem will eventually snowball into a catastrophic crusher failure.
