Pulp and paper

SPM has supplied condition-monitoring solutions to the pulp and paper industry for many years. Our first customers were North European paper mills at the beginning of the 1970s.

Condition monitoring is a cornerstone in the asset management of pulp and paper plants. Having control of the operating condition is a must to optimize plant profitability. Maintaining availability, maximizing fore-warning time, and avoiding secondary damages are the main reasons for applying condition-based monitoring in pulp and paper.

Typical applications in pulp and paper are conveyor belts, chippers, chip classifiers, blowers, screw conveyors, refiners, pressure screens, agitators, nip monitoring, felt rollers, spreader rolls, suction rolls, yankee cylinders, drying cylinders, vacuum pumps, realers, and also electrical motors, pumps, fans, and gears.

"We continue to invest in SPM equipment to increase plant availability by avoiding bearing damage that may develop into failure."

Andreas Lindblom, Maintenance Manager of the mechanical workshop at Södra Cell Värö

Digester condition monitoring for improved productivity

Whether the outlet device is hydraulic or gear-driven, SPM offers an unmatched reliability solution for digesters. The solution monitors the bearings that support the bottom scraper and shaft, where damage may develop quickly, with potentially disastrous consequences.

Benefits of the condition-monitoring solution for digesters:

  • Minimized production downtime
  • Maximized productivity
  • Less secondary damage
  • Reduced cost

Technical Solution: Digester
