As has already been pointed out, the Herrenknecht TBM produces rock chip muck NOT a ground fine product. How well do you treat that with lime?

When tunnelling with a Gripper TBM, a rotating cutterhead equipped with disc cutters is pressed against the tunnel face with a pressure of up to 32 tonnes per disc. Due to the rolling movement of the cutter, single pieces – so- called chips – are broken out of the rock. Water jets can cool the cutting tools and reduce dust formation. Buckets installed at the cutterhead take up the excavated material, which slides to the center of the machine via integrated muck chutes while the cutterhead rotates, and then falls through the funnel-shaped muck ring onto the machine belt. From there, the rock chips are passed on via further belt conveyors or transport vehicles and removed from the tunnel.
