IHydrocyclone iyisisetshenziswa sokuhlukanisa uketshezi oluwuketshezi oluvame ukusetshenziselwa ukwelashwa kwamanzi okukhiqizwa ezindaweni zikawoyela. Isetshenziswa kakhulu ukwehlukanisa lawo maconsi kawoyela amahhala amiswe oketshezini ukuze ahlangabezane namazinga adingekayo ukuze alahlwe yimithethonqubo. Amandla aqinile e-centrifugal akhiqizwe ukwehla kwengcindezi ukuzuza umphumela wokushwiba ngesivinini esiphezulu oketshezini olukushubhu lesivunguvungu, ngaleyo ndlela ephushela uketshezi olusindayo (amanzi) endaweni engaphakathi, kuyilapho uketshezi olulula (amafutha) lumpintsheka phakathi nendawo yeshubhu yesishingishane. Nge-gradient yokucindezela kwangaphakathi ebese isunduza uketshezi olusindayo (amanzi) lushona phansi kuyilapho uketshezi olukhanyayo (amafutha) luye phezulu. Kanjalo, izinhlayiya zikawoyela ezinamandla adonsela phansi alula zihlukaniswa emanzini okuphakelayo futhi zifinyelela inhloso yokuhlukaniswa kwamanzi kawoyela. Ama-Hydrocyclones asetshenziswa kakhulu ku-petroleum, embonini yamakhemikhali, ekuvikelweni kwemvelo nakweminye imikhakha noma izimboni. Angakwazi ukuphatha kahle uketshezi oluhlukahlukene olunamandla adonsela phansi ahlukile, athuthukise ukusebenza kahle kokukhiqiza futhi anciphise ukukhishwa kwezinto ezingcolile.
