Thiessen Team USA, a manufacturer of dry bulk shotcrete in Elko, NV and Big Timber, MT, commissioned Team Mixing Technologies Inc. to design and commission this automated bulk shotcrete plant at Newmont’s Midas mine in Nevada.

Thiessen Team’s bulk dry shotcrete is offloaded via a screw conveyor and bucket elevator into a horizontal hopper. An internal screw in the hopper feeds a mixing screw where water is introduced, thus preparing wet shotcrete.

The wet shotcrete is dispatched directly into a Normet transmixers for transport underground. Shotcrete is then used for stabilization of the underground workings.

The system is fully automated including an auto-wash cycle following each batch of shotcrete.
