Case studies

Pinion bearing damage in ball mill

Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the open-pit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.

Bearing damage on press roll

At Romanian paper mill Vrancart S.A., the online system Intellinova Compact with HD condition monitoring technology is installed to monitor the press section of paper machine K25. This case study involves the detection of bearing damage on one of the press rolls, showing the development of the damage over a period of about six weeks.

Condition monitoring on ball mill

Using the handheld instrument Leonova Emerald and DuoTech accelerometers, Norwegian mining company Rana Gruber monitors the mechanical condition of the production-critical ball mill in this case study.

Multistage gearbox failure

Part of a comprehensive project investigating and determining best practices for gearbox monitoring with HD technology, this case study involves condition monitoring of a multi-stage gearbox in a pulp mill.

Online monitoring on rotary calciner

This materials processing plant replaced its previous vibration monitoring system on the low-speed calciner drum with the online system Intellinova Compact after a test installation involving SPM HD measurements had proven successful.

HD Technologies on couch roll

This case study shows comparative measurements between SPM HD and HD ENV on a couch roll bearing in paper machine K25 at Romanian paper mill Vrancart S.A. Adjud.

Outer race damage in Chemi-Washer

This case study from Bulgarian pulp mill Svilocell is about the detection of a bearing damage through route-based condition monitoring on a Chemi-Washer, using the portable data analyzer Leonova Diamond.

Online monitoring of autogenous mill

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.

Ultra-long forewarning on drying drum

An international chemical company in Finland has monitored the condition of low-speed drying drums since 2012 using HD technology. This case study describes the detection of a bearing damage whose development was monitored over the course of three years.

Wash press monitoring with SPM HD

This case study describes test measurements performed on an 8 RPM wash press in the bleaching plant at Zellstoff Pöls AG in Austria using the SPM HD method.

HD technologies on ball mill at Orcem

Dutch cement producer Orcem implements HD technologies to monitor the mechanical condition of a ball mill, which is a critical part of the milling process in cement manufacturing. In many cases, the entire process can be severely limited or completely stopped if the ball mill ceases to operate. Close observation of mill equipment condition is thus essential.

Jaw crusher monitoring with SPM HD

Mining operations include a number of critical applications which may cause severe disruptions in the production process in case of malfunctions. One such piece of equipment is the jaw crusher.

Low speed bearing monitoring on low-pressure feeder

This case study deals with the implementation of condition monitoring on a low-pressure feeder in one of Sweden’s biggest pulp mills, Södra Cell Mönsterås.

SSAB: bearing condition on continuous casting line

SSAB, Swedish steel manufacturer of hot and cold reduced strip, recently has equipped its Continuous casting line 5 with online condition monitoring using Intellinova Compact and the SPM HD measuring technique.

Vibration monitoring on paper machine calender

Swedish paper mill Stora Enso Kvarnsveden applies vibration monitoring on the PM8 super calender to optimize its operation and extend the service life of the rollers.

Online condition monitoring on Boliden mine hoist

At the Renström mine in northern Sweden, Boliden monitors the mechanical condition of the multi-rope friction hoist using a combination of vibration and high definition shock pulse measurement.

Low-speed autogenous mill at Boliden mine

On an autogenous mill in Garpenberg, Sweden the Intellinova online system monitors the condition of the motors and gearboxes using vibration measurement in combination with SPM HD.

SPM HD on low speed machinery in paper production

Ortviken Paper Mill in Sweden, owned by SCA, produces coated publication papers, LWC and newsprint on four paper machines with an annual production capacity of 850.000 tons. For Ortviken, SPM HD® measuring technique is the solution to years of problems with bearing related breakdowns on low RPM machinery like the twin wire presses, which are used for dewatering of the pulp.

Hallsta Paper Mill measures bearing condition with SPM HD

"Since April 2009, we have been engaged in a project together with SPM, where we have measured bearing condition on four of our twin wire presses with SPM HD® measuring technique. To maintain pulp quality, it is essential that these presses work properly. Any breakdowns also lead to major costs for damaged rolls."

Online condition monitoring on a coal-conveyor

In Amarillo, Texas, USA, energy-services provider Savage is successfully employing state-of-the-art online condition monitoring on a coal-conveyor system to help eliminate concern of equipment failure and ensure safe and uninterrupted supply of fuel to Xcel Energy’s Harrington Generating Station.

Online monitoring in Swedish windfarm Slitevind

Slitevind AB wanted to install a system that could prevent the high cost of replacement of damaged gears in the wind park.
