Hydrocyclone ndi chida cholekanitsa chamadzimadzi chomwe chimagwiritsidwa ntchito popanga madzi opangira mafuta m'minda yamafuta. Amagwiritsidwa ntchito kwambiri kulekanitsa madontho amafuta aulere omwe amaimitsidwa mumadzi kuti akwaniritse zofunikira kuti atayidwe ndi malamulo. Amphamvu centrifugal mphamvu kwaiye ndi kuthamanga dontho ndi kukwaniritsa mkulu-liwiro swirling zotsatira pa madzi mu chimphepo chubu, potero centrifugally kukankhira katundu madzi (madzi) kuti pamwamba pamwamba, pamene kuwala madzi (mafuta) ndi cholizira pakati pa chimphepo chubu. Ndi kuthamanga kwa mkati komwe kumakankhira madzi olemera (madzi) akusunthira pansi pomwe madzi owala (mafuta) kupita mmwamba. Momwemonso, tinthu tating'ono ta mafuta okhala ndi mphamvu yokoka yopepuka imasiyanitsidwa ndi madzi odyetsa ndikukwaniritsa cholinga cholekanitsa madzi ndi mafuta. Ma Hydrocyclones amagwiritsidwa ntchito kwambiri mumafuta, makampani opanga mankhwala, kuteteza chilengedwe ndi magawo ena kapena mafakitale. Amatha kuthana bwino ndi zakumwa zosiyanasiyana zokhala ndi mphamvu yokoka, kukonza magwiridwe antchito komanso kuchepetsa mpweya woipa.
