Oct 30, 2017· The flow phenomena analysis in the hydrocyclone shows that manganese particles moves along with the wall by centrifugal force toward the underflow pipe, and the relatively less dense water and fine particles flow adversely in the vortex finder and flow out toward the overflow pipe
Hydrocyclones are widely used in the mineral processing industry as classifying or dewatering units In general, grinding circuits use a cluster of 5 to 15 hydrocyclones of diameter 50 to 75cm The slurry from the grinding mill is diluted below 65% solids by weight before it is pumped to the hydrocyclon The hydrocyclone yields an underflow stream of approximately 70-75% solids by weight and .
The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate In this tutorial example, the v2-f turbulence model is used to simulate the flow in a hydrocyclone The v2-f turbulence model, which is an extension of the k-ε turbulence model, provides highly accurate solutions for flows with strong .
Sudden changes in pressure should always be investigated because they indicate a change in the flow rate to the Hydrocyclone This may be caused by upstream equipment failure (such as a pump), damage to the Hydrocyclone or an obstruction Swings in the pressure indicate surging in the flow, which could be caused by issues with a sump
