For SCA Ortviken, SPM HD measuring technique is the solution to years of problems with bearing related breakdowns on the twin wire presses, used for dewatering of the pulp. None of the monitoring systems installed in the mill provided a dependable method for detection of bearing wear and damage, and bearing replacements therefore were carried out in conjunction with timebased maintenance.The lack of reliable bearing condition information often lead to the dismounting of the wrong bearings, in turn causing breakdowns on other bearings in worse condition.Then in the summer this year, the Intellinova online system with SPM HD was installed on Ortviken’s four Andritz twin wire presses. Following a short period of system calibration, six bearing damages have been successfully identified to date. Four bearings have been replaced during planned stops and two more will be replaced in the near future. Examination of the replaced bearings have verified that the system does indicate the correct type of bearing damage, and bearing replacement costs are now significantly reduced.
