The Valley laboratory Beater is an international standard equipment for papermaking laboratories. It is an indispensable equipment for studying the pulping and papermaking process.

Standards: ISO 5264/I, TAPPI-T200 and GB7980-87

Model: ZS-DJ-023

The Valley beater uses the mechanical force generated by the flying knife roller and the bedknife to process various fiber slurries. Cutting, crushing, kneading, splitting, wetting and swelling and fiber thinning, and at the same time, the fiber produces cell wall displacement and deformation, and the rupture of the primary wall and the outer layer of the primary wall. According to the pressure on the bedknife and the time of beating, the changes of pulp with different beating degrees can be obtained. The Wali beating machine is widely used in the beating test of various plant fibers, synthetic fibers, carbon fibers, and glass fibers. It is a papermaking production test, Indispensable papermaking experimental equipment for quality control, process development, teaching and research experiments.

This equipment meets the ISO 5264/I, TAPPI-T200 and GB7980-87 of the laboratory Valley beater method (Pulps-laboratory beating-Valley beater method) and other standards. This model can change the heavy thallium pressure, beating time, and automatically control the beating time to obtain different experimental results.

Working principle

The metered pulp with the specified concentration is beaten between the flying knife and the bottom knife of the Valley beater. During the beating process, samples are taken at intervals and the freeness of the pulp is measured.
