    Valley beater

    Overview Products Knowledge Standards
    The Valley beater cuts fibers by rotating the fly knife against the stationary bed knife, causing the fibers to fibrillate and brush out, thereby altering the pulp properties. It is used in the papermaking industry for beating treatment to adjust the drainage properties of the pulp and the strength of the resulting paper.
    Selection
    When selecting, consider the compatibility of the pulp type with the blade material, determine the capacity specifications based on production requirements, evaluate the equipment structure by combining energy consumption and maintenance costs, and adjust the pulping gap and pressure parameters according to process requirements.

    Application of Valley Beater in Pulp Laboratory Beating
    The Valley beater is a device used in laboratories to simulate industrial beating processes. It modifies the morphology of pulp fibers through mechanical action, thereby influencing paper properties. During operation, parameters such as beating pressure, pulp consistency, and beating time must be controlled, with the beating degree serving as a quantitative measure of the effect.
