The angle The key difference between the centrifuges and Liquid to Liquid Hydrocyclones that the Hydrocyclones are passive separators where it capable to apply the modest amounts of centrifugal force but the centrifuges are called dynamic separators which are generally able to concern more centrifugal force than The Hydrocyclones
For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant If the cyclone feed pump is allowed to SURGE the up and down pressure will cause poor separation at the point of high and low operating pressure There is a cycle to a surging pump box that causes this pressure fluctuation
GN solids control also provide big diameter hydrocyclone separator and customized configuration on Desander Desilter as well as mud cleaner The desander hydrocyclone can be 8” 10” 12” and desilter ones can be 4” 5” 6” Number and diameter size both can be customized accordingly 2 Inlet diameter
