ABB launched the first laboratory fiber analyzer

六月 29, 2016

ABB has launched the first laboratory fiber analyzer that has the capability to accurately detect the amount of crill in any pulp mixture. L&W Crill is an optional module to the portfolio of ABB’s fiber analyzers, as the company says in the press release received by Lesprom Network.

It uses a method based on the fact that small particles absorb and scatter light, which makes it possible to detect very small particles in a pulp suspension. It expands ABB’s offering of Lorentzen & Wettre products for fiber testing.

Crill is an important variable to measure in pulp mixtures, as these tiny fibers contribute to overall paper strength and end product quality.

L&W Crill analyzes pulp suspensions to monitor refining and dewatering. Refining the pulp increases the L&W Crill quota. During the refining process, the fibers are affected in different ways. For example, the fibrils of the fiber walls are exposed to a certain degree; these fibrillary particles on the fiber wall are described by crill. With this added capability, the L&W Fiber Tester Plus can now provide all information needed to understand pulp composition, including fiber length, fiber width, shape factor, fines content, fibril index and crill.

Because L&W Crill is not based on image analysis, it is not limited by the resolution of an imaging system. Instead, L&W Crill analyzes how particles with different diameters absorb and scatter light of different wave lengths. By sending UV-light and IR-light through a pulp suspension, it detects if small particles are present in the solution.
