  • Flow Aids
    supplier logo

    Bolz, Servolift and CORA offer a wide arrangement of flow aids to keep difficult powders moving in your hoppers.

    Vibrators:

    We offer special designs for all hopper types in both impact and vibrating type mechanisms. We focus on easy to clean solutions (GMP) with robust mounts for long term use.

    • Drum Funnel Vibrators
    • Bin (IBC) vibrators
    • Hopper vibrators

    Vibrators can not only aid flow but are often used to help clean out the funnel/hopper after full discharging of the powder. In general terms, a vibrator should not be used full time during discharging of powders if particle segregation is a concern.

    Bridge Breakers:

    We offer both manual and powered bridge breakers, these are generally used for drum funnels or on our Universal Drum Clamping Lifters in Mobile or Stationary design. In all cases the system will disassemble without tools and not leak powder.
