Weighing systems

ANDRITZ offers a range of weighing systems for use in different steps in the feed production process.

Our weighing systems are, among other things, suitable for weighing of raw material and micro and macro ingredients weighing.


Hopper weighing

Weighing is carried out by dosing in hopper scales and used for individual constituents of formula mixtures. Precise and fast weighing with the possibility of two weighing aggregates optimized the weighing process. This contributes to a faster feed of the further production flow and thereby increases output.

Advantages of the system

  • Dust-tight design
  • Fully electronic operation
  • Efficient emptying
  • Modular design
  • Suitable for weighing of individual constituents or formula mixtures

Micro and macro ingredient weighing system

The micro and macro ingredient weighing system is used for dosing of vitamins and nutrients in the feed compound. Batch weighing of micro ingredient according to recipe in a fast and accurate process helps avoid cross-contamination and ensures nutritious feed pellets.

Advantages of the system

  • Great weighing accuracy
  • Flexible formula composition
  • Fully automatically controlled process
  • Flexible building-in
  • Dust-tight design

Loss-in-weight system

The loss-in-weight system is suitable for weighing of mealy products/crumbles for liquid addition to for example a pellet mill and vacuum coater.

Advantages of the system

  • Accurate liquid addition in proportion to material quantity
  • Correct liquid dosing at increase/decrease in plant throughput
  • Great weighing accuracy
  • Dust-tight system
  • Automatic error signal at irregularities, e.g. material bridge building
