The Slalom system is a rational and economic way to store slurry for use when required. The system includes a sluice gate and TBM mixer, making it possible to keep the slurry in circulation and avoid the formation of crusts. The sluice gate, available in either galvanized steel or stainless steel AISI 304, can accommodate TBM mixers from 5.5 to 18.5 kW.
