Application range:
The 23-liter Hollander beater (Valley beater) is an international standard equipment for papermaking laboratories and is an essential equipment for studying pulping and papermaking processes. The machine uses the mechanical force generated by the flying knife roller and the bottom knife to cut, crush, rub, split, swell and refine various fiber pulps, waste paper, etc., and at the same time cause displacement and deformation of the cell wall of the fiber, and rupture of the primary wall and the outer layer of the secondary wall. According to the pressure on the bottom knife and the beating time, pulp with different beating degrees can be obtained to study the performance of pulp and formed paper sheets. The Valley beater is widely used in pulping tests of various plant fibers, synthetic fibers, carbon fibers, and glass fibers. It is an indispensable papermaking experimental equipment for paper production testing, quality control, process formulation, and teaching and scientific research experiments. The machine meets the requirements of ISO 5264/I, TAPPI-T200 and GB/T24325-2009 Pulps-laboratory beating-Valley beater method. This machine can change the weight pressure, beating time, and automatically control the beating time to obtain different experimental results.
