Product Introduction:

The 23 liter Valley beating machine is an international standard equipment in the paper laboratory and an essential equipment for studying pulp and paper making processes. It cuts, crushes, rubs, splits, moistens, and refines various fiber slurries through the mechanical forces generated by the flying knife roller and the bottom knife. At the same time, it causes displacement and deformation of the cell wall and rupture of the outer layer of the primary and secondary walls of the fibers. According to the pressure applied to the bottom blade and the beating time, the changes in pulp with different beating degrees can be obtained. The Wali beating machine is widely used for beating experiments of various plant fibers, synthetic fibers, carbon fibers, and glass fibers. It is an indispensable papermaking experimental equipment for papermaking production testing, quality control, process formulation, teaching and research experiments. This machine meets the requirements of ISO 5264-1-1979 "Laboratory beating of pulp - Part 1: VALLEY beating method"; TAPPI T200 SP-2001 Pulp Laboratory Beating (VALLEY Beating Method); GB/T 24325-2009 "Valley beating machine method for laboratory beating of pulp". Waiting for standard requirements. This model can change the heavy thallium pressure, beating time, and automatically control the beating time to obtain different experimental results.
