Refining and deflaking

Improved stock quality through effective fiber treatment

    Fiber treatment includes the most important actuating elements in terms of disintegration and surface treatment of each single fiber. Deflaking breaks up fiber bundles to prevent sheet brakes, thereby directly improving the paper machine runability. Refining increases the specific fiber surface of each single fiber resulting in higher strength potential due to fiber-fiber bonding and higher chemical absorption capacity.
     

    Voith is the market leader for compact disk applications in the field of fiber treatment. Disk applications provide very good accessibility, enabling a fast and secure filling change with low downtimes.

        TwinFlo

        Handling fiber in a uniform and highly efficient fashion

        The TwinFlo double-disk refiner can effectively handle various fibers since it can be individually set by a multitude of available fillings. Targeted technological refining of primary and secondary fibers is the main task of the TwinFlo. It is characterized by electro-mechanical setting of the refining gap with central force transmission, the greatest possible flexibility with groove and knife geometry, and uniform filling wear due to hydraulic limiting factors in the disk refiner. Changing fillings is quick and easy.

        The TwinFlo refiner is used in both fresh fiber lines as well as in secondary fiber lines. Due to the extensive assortment of fillings, suitable refining plates are available for nearly every application.

        Your benefits with TwinFlo

        • Optimal fiber treatment due to low-intensity refining
        • Proven reliable technology
        • Quick filling replacement due to easily accessibility

        Deflaker

        Energy-efficient disintegration of fiber bundles

        The deflaker family brings about optimal separation of fiber bundles in virgin pulp and recovered paper pulp preparation through acceleration and delay processes. Process efficiency can thus be improved.

        The proven filling design of the Voith deflakers allows the disintegration of wet-strength paper components and prepares machine broke. Thanks to its hinged cover, it is easily accessible and has no refining effect.

        Four variants are available with nominal volume flows between 1,000 and 8,000 l/min and a reliable motor output of 90 to 800 kW. Thanks to the improved quality of the fiber suspension, the paper machine has fewer web breaks and therefore higher machine runability.

        Your benefits with Voith deflakers

        • Low specific energy requirement
        • Intensive acceleration and deceleration of the stock for optimum deflaking
        • Less breaks on the paper machine
        • Quick filling replacement
        • No refining effect
        • Improves the efficiency of your processes
