MBF - Volumetric Micro-Batch Feeders
Download Product Brochure
The increase in cost of powders and handling of the same has resulted in more research into contamination-free feeding at
highly accurate feed rates.
Our long established position in feeding and micro-feeding and our technical know-how and facilities allow us to satisfy a
great variety of customer requirements. We take pride in having produced a competitively priced Micro-Batch Feeder of
unsurpassable performance, with the additional benefit of being highly efficient and easy to clean.
Description and Function
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 in 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 have been carried out to establish optimum body geometry. Agitator and feeder tool
geometry and materials have also been tested before choosing an optimal steel and engineering SINT® polymer composite.
MBF series Micro-Batch Feeders are supplied in food-grade versions with FDA-approval on request.
MBF series Micro-Batch Feeders for powder and granular product feeding are particularly suitable for poorly flowing materials
which tend to clog, along with adhesive products.
Fed through a bag opening hopper, a bulk bag discharger, or another feeding device, the agitator tool manages to keep the
material flowing reducing at the same time the possibility of formation of lumps or bridges.
The size of the product particles is of utmost importance when choosing the type of feeder screw. For example, fine, heavy
materials call for tapered screws with reduced pitch flights, while granular, lighter materials require standard pitch
cylindrical screws. Poorly flowing products with cohesion or bridging problems are homogeneously fed into the feeding zone
by the blending shaft which is shaped according to the product properties.
Depending on the user’s individual requirements, MBF Micro-Batch Feeders can be supplied with alternative feeder screws and
blending tools and with various accessories.
MBF Micro-Batch Feeders have been successfully operating in the following industries: food, building, plastics, chemicals,
packaging, environmental technology.
