Valley beater

Valley beater is an international standard equipment for papermaking laboratories and 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. Valley beater is widely used in beating tests 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 scientific research experiments.

The machine can change the weight pressure, beating time, and automatically control the beating time to obtain different experimental results 

Test Standard: ISO 5264/I, TAPPI-T200, GB/T24325-2009 Pulps-laboratory beating-Valley beater method.
