The Brabender FlexWall®Plus Feeder is a universal, super compact screw-type metering feeder capable of reliably and accurately metering virtually all flowable bulk ingredients. Its flexible polyurethane hopper agitated by external massage paddles makes it independent of stirring agitators. To optimise bulk ingredient flow and to minimise floor space requirement the feeder was given a trapezoidal shape.
Beside the paddle agitation principle, the steep and divergent hopper walls, a huge inlet zone without bottlenecks and steep-walled extension hoppers ensure real mass flow without bridging or ingredient depositing. In addition, the trapezoidal shape results in enormous floor space savings allowing up to six feeders - also of different sizes - to be compactly arranged around a central feed point.
The feeder is designed for quick dismantling and easy cleaning. Operation, maintenance and service do not require lateral feeder access so that in multiple feeder arrangements feeders can be placed directly side by side.
The Brabender FlexWall®Plus Feeders is available as a gravimetric loss-in-weight feeder with a built-in digital load cell ("DigiMASS-2") using the principle of two vibrating wires to compensate physical interferences, or as a volumetric metering feeder. Options include versions with hinged motors for quick screw removal from the rear and models with separate paddle motors to allow paddle speed adjustment for difficult flowing ingredients.
For processes with high demands on hygiene, e. g. for the food industry, the feeder line comprises special hygienic designs. All gravimetric versions of the Brabender FlexWall®Plus Feeder are also availble as "intelligent" weigh-feeders with built-in regulation and control electronics for direct connection to host/PLC systems or/and to Brabender touch screen operator interfaces.
