Norwegian cardboard producer Ranheim Paper & Board started up PM5 at its Ranheim paper mill after a dryer section rebuild supplied by Toscotec. The rebuild has been completed according to schedule. Shortly after, Ranheim Paper & Board has placed a new order with Toscotec for the second phase of PM5's technological upgrade, which is scheduled for autumn 2024. PM5 produces greyboard and coreboard in the basis weight range from 220 to 540 gsm.
This start-up concludes the first phase of the rebuild of PM5's dryer section. The target of improving the production efficiency of the dryer section by better controlling the felt tensions and felt guiding has been fully accomplished. Toscotec also re-designed several felt loops to be internal and thereby improved the machine's cleanliness.
The second phase will attain the highest felt tension in the dry end. The existing long shaft drive system of PM5 will be upgraded, with the application of a silent drive concept in the dryer section. Toscotec will also supply a completely new electrical drive and related control system for the entire paper machine. The service package includes the full erection with supervision, training, commissioning, and start-up assistance.
Founded in 1884, Ranheim Paper & Board has a long history as an innovative papermill and one of the world's most northerly papermills. Following the restructuring of Peterson Packaging group in 2016, the company was named Ranheim Paper & Board, which is owned today by Fundermax. It currently has 215 employees and a production capacity of approximately 120,000 tpy of paper and 50 million m2 of solid board.
