ABB expands its offering for pulp measurements with L&W Crill


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. 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.
