The underflow spray angle allows easy identification of the hydrocyclone's operating condition. The first operating condition is called 'splash', where slurry is discharged from the underflow of the hydrocyclone in a wide spray pattern. This is a normal and safe classification condition. Ideal operating condition two: Semi-roping

Hydrocyclones are centrifugal devices used to perform the separation of a discrete phase (solid or liquid) from a continuous one. Depending on the process goal, particle classification, or thickening, it is possible to enhance the performance of these devices by optimizing their geometric relationships.

Date: From: Longding Author: admin. The hydrocyclone feed pressure is provided by the feed pump, which should generally be kept within the calibration range (0.1-0.12Mpa). Therefore, the supply pressure of the pump must be kept stable during use to avoid pumping out of the pump pool and fluctuations in the pressure gauge of the cyclone.
