Chokhuthala cha ng'oma chimagwira ntchito ndi njira yozungulira yokhuthala ng'oma kuti chipeze zotsatira zabwino kwambiri pa mankhwala.
Ndalama zogulira malo, zomangamanga ndi ntchito zonse zasungidwa chifukwa makinawa amatenga malo ochepa chifukwa cha kapangidwe kake kosavuta, zofunikira zochepa zoyendetsera madzi komanso kugwira ntchito yokha.

Zotsatira zake, matope amakhuthala. Mphamvu yogwiritsira ntchito matope athu ozungulira a ng'oma imawonjezeka, ndipo nthawi yogwirira ntchito imachepetsedwa. Madzi olekanitsidwa amatha kuchepetsa kwambiri katundu wa lamba kuti alowe m'madzi. Pakadali pano, gulu la matope limapangidwa mwamphamvu. Palibe vuto la kusefukira kwa madzi kapena kusefukira kwa madzi m'mbali lomwe lidzachitike. Kenako, mphamvu ya madzi m'thupi imawonjezeka, ndipo kuchuluka kwa madzi kumachepa. Pambuyo polekanitsidwa, kuchuluka kwa madzi olimba m'madzi omasuka kumasiyana kuyambira 0.5‰ mpaka 1‰, zomwe zimagwirizana kwambiri ndi mlingo ndi mitundu ya polima.

Chokhuthala cha ng'oma chozungulira cha semi-centrifugal chimatha kusefa madzi omasuka pogwiritsa ntchito mphamvu yakunja. Chili ndi zofunikira kwambiri pa polima ndi mphamvu yomangirira ya matope. Poyerekeza ndi makina okhuthala a lamba, chokhuthala chathu cha matope chozungulira chingapereke matope okhuthala okhala ndi madzi ochepa. Madzi okhuthala okhala ndi madzi opitilira 1.5% ndi chisankho chabwino.
