Schopper pneumatic freeness Tester

The Schopper-Riegler freeness tester uses compressed air to drive pulp through a standard sieve, measuring drainage time or volume to evaluate pulp drainage performance. It is used in the papermaking industry to assess the degree of pulp refining and guide production adjustments.
Selection
Select the measurement range based on the type of slurry, consider matching the sample processing capacity with the instrument's capacity, check the stability of the gas source, confirm that the screen specifications are consistent with standards, ensure the operation interface is simple and easy to read, and ensure that maintenance parts are adequately supplied.
