The MBF range of Microbatch Volumetric Feeders provide accurate volumetric feeding of powder and granular materials.

The MBF Microbatch Feeder for continuous volumetric feeding of powdery or granular materials consists of a Stainless Steel or Reinforced Polymer Body, a horizontally mounted rotating agitator tool, a feeder screw, a feeder pipe enclosing the protruding feeder screw and one geared motor drive unit each for agitator and feeder screw.

WAM has tested product flow and material stress to establish optimum body geometry for feeding powders and granules, even those that tend to clog.
On request, MBF series Micro-Batch Feeders are supplied in food-grade versions with both FDA and EN- approval.

  • Stainless steel body, Agitator tool and Feeder screw.
  • Various agitator tool and feeder screw attachments to achieved desired flow rates.
  • Available with Horizontal or Vertical spout outlets.
  • Available with food-grade and Hazardous Zone Rated versions.
  • Three standard body sizes, Throughputs of up to 6m³ / hr.
  • Integration with a loss in weight system or VSD can provide automated accurate batching systems.
  • Minimal clearance between screw flight and feeder pipe for high accuracy.
  • Simple and quick cleaning due to non-stick SINT engineered polymer lining and quick access panel.
