Brabender Technologie GmbH & Co. KG

The Brabender BagDumper is a dump station for bagged bulk ingredients that can be extended from a simple bag dump hopper to a sophisticated bulk ingredient metering station. The modular design allows to add options like a glovebox for dust-free bag emptying inside the closed bag dump station or an attached filter refeeding filtered particles back into the system.

For poor flowing ingredients a version can be supplied equipped with a Brabender bin activator BAV. The defined discharge rate makes this variant also perfectly suitable for storage and loss-in-weight feeder refilling.

For metering directly from the bag dump hopper, the BagDumper is available with a built-in Brabender FlexWall® feeder. Variants like this additionally mounted on load cells can be used as loss-in-weight feeders for continuous or discontinuous gravimetric metering directly off the bag dump hopper. Such weighed versions are also frequently applied for filling level monitoring.

The Brabender Bin Activator "BAV" is a vibratory discharge aid ensuring a constant bulk solids flow even in case of poor flowing bulk ingredients and if silo diameters are large but outlet cross sections are small.

The bin activator consists of a discharge cone with an integrated baffle support, which is supended from a silo-welded flat ring by horizontally flexible hanger arms. An unbalance motor generates a horizontal circular vibration of the suspended part and induces active mass flow of the bulk solids and reliable discharge through the annular gap between the silo cone and the baffle support, which carries the bulk material column, thus relieves the outlet and prevents block-ups.

The highly flexible, seamless PUR transition sleeve between the flat ring and the discharge cone ensures optimum vibration isolation from the silo.

The dust-tight transition sleeve between the flat ring and the discharge cone is secured by a safety connection offering high overpressure and underpressure proofness already with the standard version. In addition, the high flexibility of the sleeve material ensures optimum vibration isolation from the silo and reduces the undesired transmission of vibration into the silo to almost none. The sleeve is made of endless polyurethane without seams.

Bin activator models available cover diameters from 600 to 1800 mm, thus offering suitable units for bins ranging from small-size hoppers to large silos, which may be made of mild steel, stainless steel, aluminium or plastics.

The Brabender Bin Activator "BAV" can be supplied made of of either mild or stainless steel. Explosion-proof versions are available.

The Brabender BagMaster bulk bag unloader is a discharge station for customary lined and unlined bulk bags. Its most outstanding feature is a unique paddle massage mechanism with two paddles, on which the bag rests. These paddles work in opposite directions and agitate both the bag outlet and the bag bottom. The paddle movement promotes reliable discharge and complete emptying also of the bag corners.

A compressed air driven Quick Docking System below the paddles provides dust-free connection of the bulk bag outlet. The outlet is clamped to the docking system manually and tautened pneumatically.

For metering directly from the bag, the bulk bag unloader is available with a built-in metering feeder, for instance the Brabender FlexWall®Plus feeder. Variants like this additionally mounted on load cells can be used as loss-in-weight feeders for continuous or discontinuous gravimetric metering directly off the bulk bag. Such weighed versions are also frequently applied for filling level monitoring. For easy bag handling the BagMaster bulk bag unloader is also available with a rigging frame or with a built-in crane runway beam.

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.

Gravimetric metering feeders from Brabender Technologie are capable of reliably and accurately metering bulk ingredients with good to critical flow characteristics. The product line includes high-tech loss-in-weight feeders and stable weigh-belt feeders.

The program of Brabender loss-in-weight feeders offers solutions for powders, pellets, flakes, chips, fibers, etc. due to a variety of ingredient suited feed mechanisms like single and twin screws, vibrating trays, vibratory mass flow feeders, rotary tubes, etc. Dependable ingredient mass flow and reliable performance are ensured by efficient agitation methods like paddle-massaged flexible hoppers or stirring agitators.

The product line is completed by an array of compact weigh-belt feeders, which are preferably used where feed rates are high and headroom is restricted. These robust feeders are capable of metering fine-grained to lumpy ingredients including materials with easily damageable particles.

Gravimetric metering feeders from Brabender Technologie are found in all bulk solids processing industries throughout the world, for instance in plastics compounding and extrusion processes and in the chemical, detergent, rubber, adhesives, food, pet food, sugar, pharmaceutical, cosmetics, life science, ceramics, construction material and glass industries.

For processes with high demands on hygiene, e. g. for the food industry, the feeder line comprises special hygienic designs. All gravimetric metering feeders from Brabender Technologie are also available as "intelligent" weigh-feeders with built-in control and speed regulation electronics for direct connection to host/PLC systems or/and to Brabender touch screen operator interfaces.
