Modeling of residence time distribution in regrinding

Modeling Of Residence Time Distribution In Regrinding

Nov 01, 2013 At present, vertical stirred mills are increasingly employed at industrial scale. The regrinding process characterization requires mixing regime knowledge along with the mean residence time of the liquid and solid phases. In this work, residence time distribution RTD measurements were performed in two different industrial flotation plants.


Fine Grinding Experience With Vertically Stirred

possibility of efficient regrinding, since ball mills are sensitive to low pulp densities and need to be operated in closed circuit with classi fiers, mostly hydrocyclones. The problem then is that the cyclones are volume dependent, so for real efficient regrinding the number of cyclones should be varied as needed, and pump capacity regulated
