Proven performance of the world’s first SALOMIX™ SSF

By: Sulzer

Ahlstrom-Munksjö is one of the world’s leading players in sustainable and innovative fiber-based solutions. In connection with an annual shut-down at the company’s Billingsfors pulp and paper mill in Sweden, Sulzer delivered its first SALOMIX SSF agitator for the swell tank. The agitator was installed in January 2020

The challenge

The swell tank is located before the final refiners, just ahead of the headbox. Therefore, high reliability, good mixing performance, and energy efficiency are key requirements for the agitator. The stock consistency is normally 3.2% with various kraft pulp types.

The solution

The SALOMIX SSF agitator demonstrated steady performance in the world’s first installation right from start-up. It was installed in the swell tank, replacing an old SALOMIX SLF agitator. The new agitator is equipped with a high-efficiency EX3 propeller, which has lowered power consumption by 10% versus the previous SALOMIX agitator with an MX4 impeller. The seal solution is water-free, using Sulzer’s grease-lubricated double mechanical seal SAC2G.

“The agitator has been running very smoothly ever since start-up. The power consumption has been reduced by about 10% with the EX3 propeller compared to the previous one.” Michael Pettersson Maintenance Engineer, Ahlstrom-Munksjö Billingsfors.

Customer benefit

The higher propeller efficiency can be utilized either for energy savings or for increasing the production capacity.

  • high reliability and smooth operation
  • water-free mechanical seal
  • compact installation
  • possibility to achieve more power savings if blade angle is reduced
