In a hydrocyclone, cut size is the separation point between particles deemed to be 'coarse' and 'fine'. If a particle is at the cut size, it will have a 50% chance of reporting to either the overflow or underflow. Any particle size greater than the cut size will exit via the underflow (coarse particles), while particles less than the cut size (fine particles) will be discharged via the ...

CFD Study on the Effect of Hydrocyclone …

An increase in overflow diameter or a decrease in underflow diameter leads to a lower separation efficiency but a clearer separation sharpness due to lower fluid underflow rate. A short-and-wide rectangular inlet is more efficient for particle separation than a tall-and-narrow one. An inclined inlet conduit plays an inessential role on the efficiency improvement but gains a 2 µm reduction in

Literature suggests that the ratio of overflow to underflow should be approximately 80:20 (Arterburn, R.A., 1982). However, the overflow:underflow ratio was closer to 20:80 with this cyclone. Because of this minor set back, we went back to the drawing board to work on Hydrocyclone 2. Design 2 Figure 2: Hydrocyclone 2 Design Adaptions.
