Swedish-based specialty paper manufacturer Nordic Paper has expanded its online vibration monitoring on paper machine PM4 at its Bäckhammar plant in Sweden. The online system will now also include the drives, with an installation comprising motor bearings and drive shafts, as well as bearings and drives in gearboxes.
The monitoring systems in Bäckhammar’s most recent installation comprises Intellinova Parallel EN, the latest and most powerful online system in the Intellinova product family, and Intellinova Compact. Intellinova Parallel EN has sixteen vibration measurement channels – all of which measure in parallel – and offers extensive flexibility for configuring complex measurement assignments. Intellinova Compact has eight vibration channels.
The installation has been ongoing during the spring and summer. The system is expected to be commissioned and in operation within the next few days when PM4 is run back up again after a planned production stop.
Nordic Paper's Bäckhammar mill has its own pulp mill and two paper machines. The pulp mill produces about 200,000 tons of unbleached pulp and the two paper machines about 130,000 tonnes of unbleached kraft paper annually.
