Witryna14 kwi 2024 · The mixing tank is important equipment for industrial applications in the wet vanadium extraction process, but in practice, there are problems, such as uneven mixing of minerals. In this study, the effect of different types of impellers and different mixing tank structures on the suspended mass of particles was simulated using the discrete … WitrynaCell-Lift impeller rotation creates a negative pressure in the hollow impeller tube causing medium to circulate uniformly in a closed loop. Cells and microcarriers are separated from the medium in the decanter column. The medium is harvested and the cells and microcarriers are transferred back to the bioreactor. high beam 2012 hyundai elantra replacement
