MBF Micro-Batch Feeders with Agitator
  • The MBF Micro-Batch Feeder for continuous volumetric feeding of powdery or granular materials consists of a steel-reinforced SINT engineering polymer body (optionally body entirely manufactured from stainless steel), a horizontally mounted rotating agitator tool, a feeder screw beneath the agitator tool, a feeder pipe enclosing the protruding feeder screw, one drive unit each for agitator and feeder screw.
  • Tests on product flow and material stress were carried out to establish optimum body geometry.
  • Agitator and feeder tool geometry and materials were tested, too, before choosing an optimal steel and SINT engineering polymer composite.
  • On request, MBF series Micro-Batch Feeders are supplied in food-grade versions with both FDA and EN- approval.
Function
  • MBF series Micro-Batch Feeders for powder and granular material feeding are particularly suitable for poorly flowing materials which tend to clog, along with adhesive materials.
  • Depending on the user's individual requirements and on material characteristics, MBF Micro-Batch Feeders can be supplied with alternative feeder screws and blending tools, with the addition of various accessories.
  • For more than four decades, MBF Micro-Batch Feeders have been successfully operating among others in the following industries: foods, building materials, plastics, chemicals, packaging, as well as in environmental technology.
Features
  • 3 sizes available.
  • Feed rates: 3 dm3/h ~ 4,000 dm3/h (0.001 ~ 2.4 cfm).
  • Body manufactured from SINT engineering polymer or stainless steel (the entire feeder may come in stainless steel with all components being interchangeable with the SINT version).
  • Agitator and feeder tool with separate drive units.
  • Due to independent drive units it is possible to select different drive powers and speeds for both blending shaft and feeder screw.
  • Wide range of interchangeable SINT engineering polymer or stainless steel feeder tools.
  • Vast range of interchangeable components: seals, feeding pipe.
  • High degree of homogeneity of the material fed.
  • Versatile, adaptable, compact, reliable, accurate.

Benefits

  • Minimum clearance between screw flight and feeder pipe ensuring high accuracy feeding.
  • Internal body geometry ensuring free flow of difficult materials.
  • Flexibility in choice of model most suitable for material to be fed.
  • Easy and quick maintenance due to limited number of components.
  • Easy and quick cleaning due to non-stick SINT engineering polymer surface and quick access panel.
Options
  • Feeders manufactured from FDA and EN-approved, food-grade SINT engineering polymer or completely in stainless steel.
  • ATEX certification.
  • Vertical outlet.
  • Pneumatic activator / electric vibrator.
  • Bag feeding hoppers with different geometries to increase storage capacity (available complete with flow aids on request).
  • Round/square bag feeding hopper with separately driven vertical agitator tool for materials that tend to pack under pressure.
  • Feeder pipe liner made from standard or food-grade SINT engineering polymer.
