Application

The 23-liter Valley Beater is a standardized apparatus used globally in paper-making laboratories. It plays a crucial role in analyzing the pulp and paper production process. The device utilizes mechanical forces from a flying knife roller and a bottom knife to perform various operations on fiber pulps, including cutting, crushing, kneading, splitting, swelling, and refining. This operation leads to the displacement and deformation of fiber cell walls, as well as the rupture of the primary and secondary wall layers. By modifying the pressure applied to the bottom knife and the duration of beating, different levels of pulp refinement can be achieved. The Valley Beater is essential for conducting beating tests on a range of materials, including plant fibers, synthetic fibers, carbon fibers, and glass fibers. It serves as a vital tool for experimental purposes, quality assurance, process development, and educational and research applications in paper production.
