Analysis of key mixing parameters in industrial Wemco …
Conclusions. Flotation performance in mechanical cells is strongly influenced by hydrodynamics. Hydrodynamics is largely driven by the action of the impeller, which is responsible for mixing in the cell. This paper evaluated key mixing parameters in three industrial Wemco mechanical flotation cells (#144, #164, #190).
