Brabender Product Lines & Laboratory Solutions
Explore Brabender bulk ingredient feeding and material characterization solutions below, or submit your process parameters for an engineering evaluation and commercial quotation.
Brabender FlexWall gravimetric and volumetric feeders are engineered for continuous, accurate loss-in-weight dosing of bulk ingredients, powders, pellets, flakes, and fibers.
The trapezoidal hopper molded from high-resilience polyurethane is massaged by external motor-driven paddles that gently knead the flexible walls, preventing bridging, rat-holing, and compacting without degrading delicate product particles.
Tool-free disassembly enables rapid cleaning, quick screw interchangeability, and minimal downtime during recipe changeovers.
These feeders excel across compounding extruders, reactor feed systems, and food processing lines, delivering uncompromised feed consistency despite variations in material bulk density.
Feed rate range 0.2 to 20,000 dm³/h, FDA-compliant flexible hoppers, ATEX explosion-proof options, AC/servo variable drives.
Brabender Twin-Screw and Single-Screw Loss-in-Weight Feeders (DDSR & DSR)
Brabender DDSR and DSR loss-in-weight feeders (including DDSR20, DDSR28, DDSR50, and DSR28 models) are designed for precision feeding of cohesive, aerated, free-flowing, and difficult bulk powders.
Co-rotating intermeshing twin screws provide continuous positive self-cleaning along the entire flight length, eliminating material adhesion and dead zones.
Interchangeable screw profiles—including open spiral, full-flight cylindrical, and blade geometries—are tailored to specific bulk densities for continuous compounding.
Heavy-duty drive gearboxes combined with air-purged shaft sealing glands protect internal bearings from abrasive dust infiltration and corrosive chemicals.
Brabender Congrav Feeder Control Modules & Operator Touch Terminals
Brabender Congrav microprocessor control electronics and touch panels deliver advanced loss-in-weight digital signal processing for multi-ingredient feeding lines.
Utilizing proprietary adaptive vibration filtering and high-frequency PID control algorithms, Congrav systems maintain gravimetric feeding accuracy within ±0.2% to 0.5%.
Congrav CB boards mount directly onto the feeder scale base, while Congrav OP1-T and OP5-T touch terminals offer intuitive graphic telemetry and seamless host PLC connectivity.
Digital communication protocols support Industrial IoT networking, remote load-cell diagnostic telemetry, and dynamic zero-point calibration without interrupting main extruder throughput.
Brabender Plastograph EC, EC Plus & Plasti-Corder Torque Rheometers
Brabender Plastograph EC, EC Plus, and Plasti-Corder Lab-Station modular torque rheometers are universally recognized instruments for testing the processability and melt rheology of thermoplastics, thermosets, elastomers, rubber compounds, and ceramic dopes.
Engineered with precision digital servo drives and dynamic torque transducers, they measure melt torque, fusion behavior, and shear energy across extensive shear rates when coupled with Brabender measuring mixers or extruders.
The MetaBridge web-based architecture empowers laboratory scientists to capture fusion curves, detect degradation thresholds, and reliably scale laboratory formulations to full-scale compounding lines.
Torque capacity up to 200–400 Nm, speed 0.2–150/200 RPM, web-based Brabender MetaBridge software with automated logging.
Brabender Measuring Mixers and Compounding Attachments (W 30, W 50 Series)
Brabender interchangeable measuring mixer attachments (net chamber volumes from 30 to 350 cm³) simulate industrial internal batch mixing, mastication, and thermal degradation of polymer blends.
The three-piece split chamber features multi-zone electrical heating, fast air/liquid cooling, direct melt temperature thermocouples, and matched counter-rotating rotor pairs machined from nitrided tool steel to process high-viscosity resins, rubber, and filled polymers.
Mixers incorporate a weighted loading chute and pneumatic ram that maintain consistent compaction pressure throughout blending, ensuring exceptional test-to-test reproducibility for resin qualification.
W 30, W 50, W 50 E chambers, Cam (thermoplastics), Roller (PVC), Banbury (elastomers), Sigma (pastes) rotors, up to 500 °C.
Brabender laboratory measuring extruders (19/25 D single screw) and Mini-Compounder KETSE 20/40 (co-rotating parallel twin screw) are engineered for R&D trials, formulation optimization, masterbatch compounding, and continuous micro-scale specimen extrusion.
The barrels feature modular multi-zone temperature control, degassing ports, melt pressure transducers, and a versatile selection of profile dies including ribbon, strand, tube, and pelletizing heads.
The clamshell horizontally split barrel on the KETSE compounder opens effortlessly, allowing direct inspection of the melting mechanism, mixing progression, and filler dispersion along the entire process section.
19/25 D single screws, KETSE 20/40 D clamshell split barrels, modular kneading blocks, strand dies, and laboratory pelletizers.
Brabender Farinograph-TS, Extensograph-E, and Amylograph-E food characterization instruments are global industry benchmarks for wheat flour testing and dough rheology evaluation.
Delivering reproducible rheological profiles, they quantify water absorption, dough development time, kneading stability, softening degree, and extensibility energy in accordance with international ICC 115/1, ISO 5530, and AACC standards.
Motorized titrating burettes and precision water-jacketed mixing bowls eliminate operator bias, guaranteeing standardized flour quality evaluation across mill laboratories and commercial bakeries worldwide.

Brabender Bin Activators, Bulk Bag Unloaders & Discharge Equipment
Brabender Technologie discharge aids and container unloading systems ensure steady bulk material flow from silos, surge hoppers, and intermediate bulk containers.
Vibratory Bin Activators (diameters 600 to 3,000 mm) eliminate bridging and rat-holing by transmitting horizontal vibrations directly into the material column via an internal baffle cone without stressing silo walls.
Bulk Bag Unloaders (BBU) feature pneumatic bottom and side massage paddles, dust-tight clamping seals, and integrated hoist frames for dependable discharge into loss-in-weight feeders.

Engineering Selection of Feeders and Laboratory Rheometers
To select the ideal Brabender Technologie gravimetric feeder for your continuous or batch compounding line, please specify your bulk material properties: bulk density, particle size distribution, moisture content, aeration behavior, and flow characteristics, alongside the required minimum and maximum mass flow rate in kg/h. Our technical team configures the proper hopper geometry (flexible polyurethane FlexWall or rigid stainless vessel with paddle agitator), screw tooling profile (spiral, full-flight, blade, or mesh screw), and load cell class. For polymer testing, we size Plastograph torque rheometers and measuring extruders to meet your polymer viscosity, target shear rates, operating temperatures, and die shaping requirements.
