By adding binding agents such as: Lime, very watery soil can be transformed into a conveyable substrate.

Two counter-rotating shafts, which are equipped with spirally arranged plates, convey the mixed material through the trough of the machine and mix it during this process. Any necessary binder is fed into the machine together with the substrate.
The mixing result is influenced by the mixer length or by the additives added.
The throughput capacity is defined by the respective size of the twin-shaft mixer. The shaft speed is an almost constant value and is therefore only of minor use for adjusting the flow rate.
