Experience in the Design and Reliable Operation of Ore-Pulp Precessional Mixers for Large-Volume Process Tanks

详细

The advantages of special smooth-wall apparatuses equipped with precession stirrers compared to typical process tanks equipped with the stiff shafts of stirrers have been shown. A one-dimensional mathematical model has been considered for describing the rotary velocity field and calculating the hydrodynamic loads used during the design of large-volume precession apparatuses for mixing ore pulps. The validity of the model has been confirmed experimentally using the literature data and a positive experience in the long-term operation of process tanks that are 50–1250 m³ in volume, which are designed for the dealkalization of high concentrations of ore suspensions of noble metals.
