From grain to feed

Batch Weigher

Batch Weighers provide fast, accurate weighing of powders and granulates before mixing or processing. Material is dosed sequentially from silos or bins into one weighing bunker, then discharged quickly via a slide or discharge chain conveyor. With an optional discharge bunker, the next batch can start filling immediately to cut cycle time. Typical capacities range from 500 to 6,000 kg, in compact or long bunker versions up to 25 m.

  • High-throughput discharge (slide or chain conveyor)
  • Suited for powders and granulates
  • Integrates with multi-silo dosing

  • Discharge methods: rapid-discharge slide; discharge chain conveyor
  • Layouts: compact weighing bunker; long bunker weigher (up to 25 m)
  • Capacities: 500–6,000 kg per batch (application-dependent)
  • Load cells: four or more (depending on bunker length and accuracy requirements)
  • Construction: painted carbon steel or stainless execution; dust-tight housing; inspection hatches
  • Options: platforms/steps, level sensors, wear liners, ATEX components, maintenance lighting, integration kits for upstream silo blocks and downstream mixers

Your questions answered

FAQ

Powders and granulates such as grains, meals, premix components and carrier materials used in feed, food or industrial recipes.

By combining rapid discharge (slide or chain conveyor) with a discharge bunker so the next batch can be filled immediately after the previous one empties.

Use a rapid-discharge slide for compact footprints and very fast emptying; choose a discharge chain conveyor for long bunkers or when controlled transfer to the next process is required.

Multiple load cells are used along the bunker length to maintain accuracy and stability during filling and discharge.

Yes. Batch Weighers are designed to receive sequential doses from screw feeders, grid-slide feeders or rotary discharge equipment and to connect directly to mixers or buffers.
