Freeness Testing of Pulp Mixtures

Ensure pulp mix perfection

Freeness of pulp is a measure of how quickly water is able to drain from a fiber furnish sample. When you run a freeness test at the right points in your process, you gain better control over drainage, retention, and refining performance.
 

The role of freeness in papermaking

Are you involved in paper making? When you need to make consistently high quality sheets, careful examination of the surface conditions and swelling of the fibers is important. A stable freeness of pulp profile helps you balance formation, strength, and surface properties across different grades.
 

Reliable tools for accurate freeness testing

Industrial Physics’ freeness testing inspection devices enable you to accurately evaluate slush pulps taken from your production lines to ensure continuity in pulp quality. Using a Schopper Riegler freeness tester, your team can track how refining and stock preparation steps are affecting drainage behavior and make quick, data-driven adjustments.
 

Consistent quality and supplier evaluation

Our accurate, reliable freeness testing machines will check the consistency of any pulp purchases you make. So you can evaluate your supplier options and select the best pulp sources to achieve the paper or board qualities you need, at the most economical cost. Routine freeness test programmes also support documentation for audits and customer specifications.
 

Supporting research, development, and process optimization

Do you need to invest in research and development to improve pulp quality, or alter your pulp characteristics to optimise paper and board product properties? Or do you want to optimise pulp blends and their treatment in stock preparations? With the right Schopper Riegler freeness tester you can run repeatable trials, compare refiners, and understand how process changes influence freeness of pulp values.
