    Anti-bridging device - Conical bottom for controlling the descent of powders and facilitating the flow of the product

    The mechanical anti-bridging devices facilitate and regulate the downflow of powders under a storage silo or hopper.
    The anti-bridging devices with conical bottom break up the clods and facilitate the flow of the material.

    They are the solutions for the issues below:

          Segregation                             Rat hole                                  Bridging                                  Retention

    There are 2 principles of conical anti-bridging:

    • Efficiency
    • Air consumption
    • Noise level

    Rotating blades:

    Conical screw:

    Rotaring blades

    Integral passage in the output flange

    The anti-bridging devices with rotating blades with conical bottom are specially designed to be clamped on hoppers containing poor flowing powders.
    The standard cone angle is 60°. It goes with two scraping rotating blades.
    Its hollow shaft conception with offset geared motor provides full bore of the bulk material in the outlet flange.
    This design makes possible the implementation of standard slide valve or butterfly valve for maintenance purposes.

    Conical screw

    To boost the flow of powders and the feeding of the extraction screw

    In order to carry out an extraction of moist and very clogging powders from a cylindrical and conical storage silo, Palamatic Process offers a mechanical fluidising system with conical screw.
    The blade, positioned at the top of the blender ensures the breaking of the sloping and optimizes the useful volume of the hopper.
    Also, the screw prevents the bulk material from caking and promotes their emptying.
    The main advantage of this anti-bridging device is the implementation of the drive motor at the top of the hopper, which protects the central shaft passage from the powders.
    The conception and the design of the screw are defined according to the handled bulk materials. The rotational speeds are slow and are less than 1 meter per second at the periphery.
    This equipment is compatible with "Clean In Place" systems and ATEX certifications.
