Customer Success Story
Saves around 200,000 USD per hour
One of the largest coal mining operators in Southeast Asia, Adaro Indonesia produces around 50 million tons of coal annually. The bearings of the conveyor belts of the open pit mining company are highly stressed in the process. To avoid unplanned downtime here, the maintenance team opts for the condition monitoring solution with SmartCheck and the associated software.
The result: per hour, a production loss of 200,000 USD for each production line is prevented and safety for the maintenance team is enhanced.
Benefits
Safe condition monitoring in real time
Less unplanned downtimes
Early detection of bearing defects
Reduced risk of injury for maintenance team
Centralized monitoring of all conveyor bearings
Intelligible data for diagnosis
Enhanced planning of resources and inventory
Challenge
Additional information on the coal mined
Adaro Indonesia mainly mines subbituminous coal. This is one of the low grades of coal containing about 35-45 percent carbon. The properties of this type are between those of lignite, the lowest coal type, and bituminous coal, the second highest coal type. Subbituminous coal is mainly used as a fuel for steam electricity generation.
Subbituminous coals have a sulfur content of less than 1 percent by weight, which makes them an attractive choice for power plants to reduce SO-2 emissions. For this reason this type of coal is also classified as „clean.“
It should be considered that this type of coal must be densely packed to avoid spontaneous combustion.
Solution
What´s special
The ease of use of the Schaeffler Smart Utility software does not require expert knowledge in vibration analysis. Thus, engineers without vibration knowledge will be able to pick up analysis knowledge and skills faster, and can then make informed decisions. The customer‘s satisfaction is expressed by Schaeffler engineer Chris Y. Hardianto:
"Thanks to SmartCheck, a production loss of around 200,000 USD per hour was prevented for each of the customer‘s 3 production lines.
Adaro Indonesia is impressed and absolutely satisfied."
