Volumetric dosing feeders

volumetric-dosing-feeders

Volumetric Feeders have an unique ability to accurately and reliably feed an extremely broad variety of dry solid ingredients.
Their innovative and technologically superior designs provide a high degree of versatile volumetric metering performance. The quality of construction and durability of these volumetric feeders is unsurpassed; their maintenance requirements are the lowest in the industry.


A true volumetric feeder encompasses a positive method of measuring a specific volume of product and a means to effectively discharge that material, generally over a variable range. With an auger type volumetric feeder, the auger is the means used to measure volume, discharging the “measured” volume of material with each revolution, as it typically rotates through a discharge spout. Consequently, the viability of any auger type volumetric feeder is dependent upon how uniformly and consistently the feed auger is filled with product, and how reliably this is accomplished. 


General volumetric feeding features

  • Output based on metering auger RPM, diameter and pitch

  • Typical accuracy 1-3% for most materials

  • Main purpose of a volumetric feeder
    - Hopper material
    - Fill metering auger consistently
    - Bring material to constant density
    - Maintain consistent flow rate

  • Volumetric feeders are installed on platform or overhead scales to become compact and rugged duty “weight-loss-differential” gravimetric weigh feeders

  • Circular, flat bottom feed chamber with self-emptying auger/agitator mechanism
  • Suitable for poor flowing products and rapid product changeovers.
  • Non-restrictive, non-converging inlet
  • Slow speed horizontally rotating agitator ensures positive flow of material to metering auger
  • Can accurately feed until virtually empty
  • Discharge chute with slide plate for fast
    product discharge
  • Designed for powder, granular and flake materials
  • Optional “Active-Hopper”
    Isolation pad and gentle high frequency vibration promotes material flow
  • Optional Quick disassembly / re-assembly
  • Optional Sanitary construction
  • Metering capacity from 0,003 up to 6,8 m³/hour
