The QS FibreScreen

The QS FibreScreen

The QS FibreScreen offers mills a quick, simple, and reliable method for determining shive, stickies or dirt concentrations in low consistency pulp samples. A masterscreen-type instrument, the FibreScreen is fully compliant with TAPPI T274 sp 13 for the Laboratory Screening of Pulp and up to 100 air-dry grams of disintegrated pulp may be screened per test cycle. Reject material may then be removed for processing through the QualScan suite with the resulting data automatically saved to a local database. Average length, average width, and total count are displayed on the monitor. User-configured histograms are called up in the Viewer module for comparative analysis.


Screening is completed 3 minutes after slurry drops below low level sensor. The discharge pinch valve opens and the screen rejects are released into the integrated Retentions Collection Unit (RCU) for weight measurement or QualScan image analysis.


The QS FibreScreen is an excellent and flexible device to support the qualitative and quantitative assessment of pulping and stock prep step processes. Operators can easily maintain an overwatch of the fibreline, stock prep and furnish to quickly detect and troubleshoot upset conditions before losing tonnes of production to off-target quality and broke.
