AC-2 dry and wet mix shotcrete machine

From 5000 EUR In stock

The AC-2 is based on the classic rotary principle with the drum revolver type.
The performance of the machine provides a large margin of safety, high reliability of accessories, and the probability of working with shotcrete materials (gunning materials) of any density, including refractory mixtures with a large angle of slope. Flexibility in use allows adapting the AC-2 to most types of shotcrete work.

  • Classic design with two sealing plates.
  • The most compact of revolver machines.
  • Reliable disk variator for smooth performance changes.
  • Conveniently works with fine-grained and powdery mixtures.
  • An extra mixer provides full mix coverage.
  • Dosing drum cells, even with wet mixes.
  • Height of loading is 1,1 m.
