Case Study: Indah Kiat Pulp & Paper Perawang achieves improved roll reliability with Valmet roll reconditioning

Indah Kiat Pulp & Paper Perawang improves roll reliability with Valmet, preventing 450,000 tonnes of annual production loss

The customer, Indah Kiat Pulp & Paper Perawang, faced challenges with an unstable calender roll at their PPM6 mill, which caused oil pressure variations, nip closing disturbances, and production time loss. To address this, they engaged vendor Valmet for its roll reconditioning service.

Valmet reconditioned the calender roll at its technology center, returning it to an "as new" condition. Following this solution, the roll's pressures stabilized, which improved machine efficiency and paper quality. The results also included enhanced environmental and occupational safety due to the elimination of oil leakages, preventing unplanned roll changes.
