Description

Medium-throughput, automatic, calibratable bagging weighers.

The material is first weighed inside the hopper scale and then transferred to the filling unit. The main benefit of this unit is the very fast cycle time with concurrent dosing and bagging operations.

Modular construction suitable for endless applications!

    – Coarse/fine dosing channel with vibrator and control valve.
    – It handles smooth and rough media like flakes, pumpkin seeds, wood chips, bulk construction aggregates etc…
  • Cleated Feeding Belt
    – Coarse/fine dosing channel with vibrator and control valve.
    – It handles smooth and rough media like flakes, wood chips, fibrous compound feed etc…
  • Product-contact Cleated Feeding Belt
    – Coarse/fine dosing channel with vibrator and control valve.
    – It handles smooth, hard-to-meter media like flakes, deep-frozen vegetables and meat etc…
