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.
