Drum thickener imagwira ntchito ndi ng'oma yozungulira kuti ikhale yolimba kwambiri.
Mtengo wa malo, zomangamanga ndi zogwirira ntchito zonse zimapulumutsidwa chifukwa makinawa amatenga malo ochepa pansi ndi mawonekedwe ake osavuta, zofunikira zazing'ono komanso ntchito zodziwikiratu.

Chifukwa chake, slurry imakhuthala.Kuthekera kwa makina athu a rotary drum sludge thickener kumakhala bwino, ndipo nthawi yogwiritsira ntchito imafupikitsidwa.Dothi lolekanitsidwa limatha kuchepetsa kwambiri katundu wa lamba kuti alowe madzi.Panthawiyi, gulu la matope limamangidwa mwamphamvu.Palibe kusefukira kwa pepala kapena kusefukira kwa mbali zomwe zidzachitika.Kenako, kuchepa kwa madzi m'thupi kumawonjezeka, ndipo kuchuluka kwa madzi kumachepetsedwa.Pambuyo pa kulekana, zolimba zomwe zili m'madzi aulere zimasiyana kuchokera ku 0.5 ‰ mpaka 1 ‰, zomwe zimagwirizana kwambiri ndi mlingo ndi mitundu ya polima.

Semi-centrifugal rotary drum thickener imatha kusefa madzi aulere pogwiritsa ntchito mphamvu yakunja.Ili ndi zofunikira zazikulu za polima komanso mphamvu yomanga ya matope.Poyerekeza ndi makina okulitsa lamba, makina athu ozungulira a ng'oma amatha kupereka matope okhuthala okhala ndi madzi ochepa.Dothi lokhala ndi madzi opitilira 1.5% ndi chisankho chabwinoko.
