Abstract

We introduce a new method of processing irregular data from any rotating machine, in particular high-consistency pulp refiners. Refiner plate bar forces and rotor absolute angle are acquired synchronously, and a fuzzy gate is exploited to filter instantaneous force events from background noise. Fuzzy gate parameters are partially justified by plate geometry. The method enables the acquisition of quantified and detailed spatial information on refiner plate bar forces, thus supporting the design of more energy efficient refiner plates and bar patterns. The study identifies key areas of application for synchronized force analysis in high-consistency pulping research.
