solids Dosing equipment

1. Filling the metering unit, resp. drawing product from store
2. Discharging the metering device, e.g. chambers, pockets, or cells, and supplying a fixed product quantity to the downstream process.

The objectives are a high volumetric metering accuracy, as well as continuity and reproducibility. Ideally, this objective is achieved by 100% filling and then 100% discharging isolated metering units.

Typical volumetric metering devices:

  • Rotary airlock
  • Micro-metering airlock
  • Metering screws
  • Vibratory metering screws with hoppers
  • PreciDos precision metering device
  • Scraper-equipped rotary airlocks
