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.
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.
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. Where accurate feeding is required for dosing and batches the MBF can be supplied with an optional loss in weight system and scales system.
WAM (MBF) Micro-Batch Feeders have been successfully operating in the following industries Globally & across Australia: food, building, plastics, chemicals, packaging, mining and water treatment (Lime dosing systems)
