Valmet Adds New Capabilities to Fiber Image Analyzer

Valmet, Finland, has added new measurement capabilities to the Valmet Fiber Image Analyzer (Valmet FS5). These features take the laboratory testing of pulp and paper fiber samples to a new level. 

Launched in 2013, more than sixty Valmet FS5 analyzers are now in use, continuing Valmet's 30 year fiber analytics history with more than 1,000 fiber property measurements delivered. Fully meeting the ISO fiber length measurement standard requirements, the analyzer is simple to use with no lengthy training needed. Easily measuring the fiber properties of 100 samples in an eight-hour shift, the automatic consistency adjustment eliminates operator error by allowing samples to be inserted without any special preparation. 

Analyzers are individually customizable, equipped with only the required measurements and easily programmable for customized analysis and reporting. Maintenance requirements are minimal and no on-site calibration is required as each unit is calibrated with an accredited calibration tool at Valmet's production center in Kajaani, Finland. 

The strength potential of the pulp can now be predicted easily from the process samples. Better understanding of the characteristics of the fibers helps papermakers to better manage the process and get targeted end product quality by optimizing the blend and using less energy, for example, in grinding.

 

"The new gravimetric coarseness feature in Valmet FS5 has been accepted very well by our customers. The true coarseness value is an important value, which predicts the paper structure and now it is possible to get this result easier and faster than ever before without tedious and time consuming sample preparation. Our approach of combining both optical and gravimetric coarseness values is a result of out-of-box thinking by our R&D - helping our customers to save time and money," said Tuomo Kälkäjä, the product manager of Valmet FS5.

Cell wall thickness and cross sectional area, available in a previous generation of Valmet's analyzer, is also now derived by the Valmet FS5, which reports average values for the whole sample. Results provide a better understanding of the papermaking potential of the pulp. 

Based on user feedback, Valmet has implemented improvements to the operator interface, including customizable measurement templates and reports. Valmet FS5 is now easier than before to use in regular mill testing, and it also meets the requirements of research laboratory use. The increased capabilities offered by these new measurements and improved interface are also available as upgrades for existing users.
