Successful online bearing monitoring of autogenous mill with HD technology

In this case study from Bulgarian copper producer Aurubis, the SPM HD shock pulse technology is used to monitor the pinion shaft bearings of a production-critical autogenous mill in the flotation plant.

The Intellinova Compact online system showed rising shock pulse levels right from the start, indicating an outer race damage. The precision of the SPM HD measurements enabled Aurubis to stay on top of the development of this bearing damage over the following eighteen months and to plan for the bearing replacement at a suitable time. After the bearing was dismounted, the damage was confirmed, as can be seen from the photographs.

Iron and steel

Condition monitoring is a cornerstone in the asset management of iron and steel plants. Having control of the operating condition is a must to optimize plant profitability.

Intellinova Compact

The high-performance Intellinova® Compact system is available in multiple versions, well suited for remote monitoring or industrial environments with groups of measuring points.


SPM HD – high-definition shock pulse monitoring in a very broad RPM range, including ultra-low-speed applications (0.1 - 20 000 RPM range).
