TWIN-MIX
Robust and flexible mixers
The mixers of the BERTOLI TWINMIX line are continuous counter-rotating dual-shaft mixers, for mixtures of consistency from moist to fluid (consistency classes from S1 to S3).
They generally equip the machines of the BERTOLI ECO-TECH line for the production of concrete, cement mixes, inerts, cold bituminous mixes.
It is possible to interface them comfortably to a suitable plant of any other manufacturer: they are equipped with an electric motor drive system and mixed transmission belt-gears.


The gearbox – like all other mechanical parts of the machine – is designed and built to ensure maximum sturdiness and reliability.
An appropriately sized system of threaded connections ensures interchangeability at the end of life (as indicated by the use and maintenance booklet in the routine maintenance section) of the internal blades and inner shields.
