The mining industry operates in an increasingly competitive and capital-intensive industry, where profit margins are slim. As technology advances and more productive equipment is brought in, a solid maintenance program is required to improve reliability and secure a maximized return on investments.

Maintenance costs are generally higher in the mining industry than in many other industries. Until recently, reactive maintenance was the predominant strategy in mining. However, in consequence of equipment failures and catastrophic breakdowns causing large production losses and rising maintenance costs, the industry has modernized its maintenance practices.

Tough terrain and difficult operating conditions are trademarks of the mining industry. Mining machinery faces challenges like heavy loads, debris, wide variances in rotational speeds and severe misalignment. The mere size of the equipment and factors like spare part delivery time has made condition monitoring increasingly important to predict breakdowns.

Typical applications in open pit mining are excavator gearboxes, conveyors and crushers, where very slow rotational speed and load variations make condition monitoring complicated.

In underground mining, applications like elevators and lifting devices typically benefit from condition monitoring. Fans that are critical for ventilation and pumps keeping control of water levels and support for drilling are other areas of application.

"The online system enables long-term planning of our maintenance work. Ultimately, our goal is to have online monitoring installed on all significant operational equipment, and we are almost there. We have chosen to further develop our SPM systems since we have good cooperation; it is easy to get in contact with the service technicians and they always provide prompt assistance"

Mats Johansson, Maintenance Manager, Boliden Renström

New unique solution to optimize grinding

The solution monitors the charge toe position at the inlet and discharge ends of the mill drum and is an effective tool for oper­ators to determine the ideal feed rate for optimal grinding efficiency and particle size distribution.

In addition to avoiding mill overload, underload, and freewheeling, further benefits include monitoring:

  • wear-and-tear on the liner and lifters
  • outlet blockage
  • density
  • big rock occurrence

Heavy-duty equipment for the mining industry

The mining industry is a heavy industry where condition monitoring equipment must survive mechanical and environmental forces. The SPM product range includes portable instruments, online systems and accessories specifically suited for shock pulse monitoring of rotating machinery and vibration monitoring equipment for detecting misalignment, gear problems, balancing problems etc. On slowly rotating machinery, the SPM HD® measuring technique can be used with benefit. SPM HD uses RPM based sampling frequency and algorithmic correlation techniques to ensure the highest possible signal quality and razor sharp spectrums for analysis.

Portable instrumentation

Our range of handheld instrumentation includes equipment for shock pulse measurement, vibration severity measurement, and vibration spectrum analysis.


With Intellinova, our unique HD condition monitoring technologies can be fully utilized to successfully provide earlier warning of mechanical problems than any other monitoring technology.

Products for Ex environment

Our high-performance portable and online equipment are also available for potentially explosive environments.

Transducers and transmitters

Selecting the right sensor for your application is vital to measurement accuracy. We offer a wide range of high-quality sensors and transmitters.
