L&W Fiber Online

Better optimize control and refining with more frequent and reliable fiber morphology measurement

 
 
 

Mills often have insufficient resources for true visibility into fiber quality. 

L&W Fiber Online is an image-based measurement system that provides an accurate and comprehensive assessment of fiber quality in real time. Compared with traditional in direct measurements, such as Schopper-Riegler (SR), the image-based measurements provide a more accurate pulp quality status in the wet end for precise optimization of fiber usage. Paper makers can easily pinpoint and follow trends on furnish quality, close the control loop, and reduce variations.

Measurements according to standards
L&W Fiber Online solves the problem of detecting quality issues too late to take action by discovering variations as early in the process as in stock preparation to take corrective action sooner and meet quality specs. This system measures fiber properties according to international standards; it is based on ABB’s well-known L&W Fiber Tester Plus. Fiber properties are categorized and presented as mean values and statistical distributions of width, length, shape factor, two classes of fines (P and S) and macro fibrillation.
