Three Factors Affect the Classifying Effect of Spiral ...

2019-9-23  The spiral classifier is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding efficiency of the grinding mill.

Experimental Investigation of Novel Enhanced Gravity ...

2019-2-18  The novel closed spiral classifier creates around 80–180 G-force. Our CFD study estimates that the shear rates in the equipment wil be of the order of 10 3 s −1, whereas hydrocyclones will generate around 10 4 s −1 at similar process conditions [ 29 ]. Thus, it may be more suitable for enhanced separation for flocculation systems.
