Brabender Twin Screw Feeders

with stirring agitators for bulk ingredients with critical flow characteristics

.

Volumetric twin-screw feederLoss-in-weight scale with twin-screw feeder

Volumetric feeder      Loss-in-weight feeder

The Technology

  • Stainless steel hopper

  • Multifunctional stirring agitator

  • Separate screw and agitator 
    motors (3-phase current)

The Advantages

  • For poorly flowing or 
    floodable ingredients

  • Ingredient homogenization

  • Uniform screw filling level

Models

  • Stand-alone volumetric feeders

  • Fully digital loss-in-weight feeders

  • Feed rates up to 5 m³/hr

* Theoretical values referring to a screw filling level and a motor speed of 100% each. Depending on the flow characteristics the screw filling level may decrease down to 50%, particularly if poorly flowing ingredients are fed. In gravimetric applications, i. e. as part of a loss-in-weight feeder, further feed rate reductions have to be taken into account because part of the upper motor speed range is required to balance bulk density variations. To identify the optimum feeder for your specific ingredient and required feed rate we recommend to make use of our automatic feeder selection program "FeederScout".
