Fliegl Bau- und Kommunaltechnik GmbH in Mühldorf offers robust mobile and stationary duplex mixers in all shapes and sizes. The "Mix Master Duplex" mixers impress with their extremely low wear when compared to conventional mixing systems – be it when preparing concrete, mortar and screed or processing gravel, sand, chippings, cement, soil, seed etc. Even earth-moist or rough, coarse-grained materials are mixed thoroughly and effectively in a very short time.

Mix Master Duplex DK

Very easy to fill by simply tilting the mixer forward; the loading bucket then opens automatically.

Benefits of the Fliegl duplex mixer compared to screw mixers

Fliegl duplex mixer

Screw mixer

  • Approx. 60% lower oil consumption on hydraulic drive motor

  • 80-90% less wear

  • Wheel loader operation with low speed

  • Reduced fuel consumption and wear on wheel loader

  • Easy cleaning

  • Actual usable volume = machine type
    e.g. 400 DK | approx. 400 l useful capacity | container volume approx. 750 l

  • Much shorter mixing times – approx. 75% time saving

  • Mixing of recycling and coarse-grained materials possible

  • Very high wear on mixing auger and bucket walls caused by rock

  • Poor mixing quality despite long mixing times

  • Extremely high oil consumption

  • Wheel loader operation with very high speed

  • Very high fuel consumption and wear on wheel loader

  • Difficult to clean

  • Specified usable volume generally not accurate in practice
    e.g. type 750 | approx. 350-400 l useful capacity | container volume approx. 750 l

  • Generally not possible


Can be attached to wheel loaders, excavators and telescopic loaders. 

Filling the mixer is child's play: 

  • Open the loading bucket simply by tilting it forward
  • Drive into the rubble, gravel or sand pile

Binders such as water and cement are added after filling the mixer. Mixing can take place while travelling to the point of use. 

Flexible application – easy and practical operation
