Screw Conveyor Supply Tbm

In EPB mode, the screw conveyor drops the excavated material onto a belt conveyor. An additional slurryfier box at the end of the screw conveyor makes it possible to drive the TBM with a hydraulic slurry circuit in slurry mode. In the latter case, either a normal bentonite suspension or a high-density suspension can be used
