ABB on-line system measures, controls pulp freeness

Zurich, Switzerland-based ABB has launched L&W Freeness Online, a reliable, repeatable and cost-effective on-line system for measuring, monitoring and controlling key quality variables — Canadian Standard Freeness (CSF) and Schopper-Riegler (SR) — in paper stock preparation. This helps mills to save production costs by reducing energy consumption by eliminating over-refining and to improve quality by generating uniform pulp furnish for paper, board or tissue machines.

ABB says L&W Freeness Online solves the problem of inconsistent and inaccurate manually-measured results with an automatic, complete measurement cycle, reporting results that are compensated for consistency and temperature, with measurement results that approach laboratory standards.

The system also allows for multiple sampling points with a single instrument, reducing initial investment and maintenance costs.
