Hydrocyclone ndi chida cholekanitsa chamadzimadzi chomwe chimagwiritsidwa ntchito m'minda yamafuta. Amagwiritsidwa ntchito kwambiri kulekanitsa tinthu tating'ono tamafuta tomwe timayimitsidwa mumadzimadzi kuti tikwaniritse zomwe zimafunikira ndi malamulo. Iwo amagwiritsa amphamvu centrifugal mphamvu kwaiye ndi kuthamanga dontho kukwaniritsa mkulu-liwiro kugwedezeka pa madzi mu chubu chimphepo, potero centrifugally kulekanitsa tinthu tating'ono mafuta ndi mbandakucha enieni yokoka kukwaniritsa cholinga cha kulekana madzi-zamadzimadzi. Ma Hydrocyclones amagwiritsidwa ntchito kwambiri mumafuta, makampani opanga mankhwala, kuteteza chilengedwe ndi zina. Amatha kuthana bwino ndi zakumwa zosiyanasiyana zokhala ndi mphamvu yokoka, kukonza magwiridwe antchito komanso kuchepetsa mpweya woipa.
