Chowumitsira rotary ndi mtundu wa chowumitsira m'mafakitale chomwe chimagwiritsidwa ntchito kuchepetsa kapena kuchepetsa kuchuluka kwa chinyezi chazinthu zomwe zikugwira pozibweretsa kuti zigwirizane ndi mpweya wotentha.Chowumitsira chimapangidwa ndi silinda yozungulira ("drum" kapena "chipolopolo"), makina oyendetsa galimoto, ndi dongosolo lothandizira (nthawi zambiri nsanamira za konkire kapena chitsulo).Silinda imapendekeka pang'ono ndipo kumapeto kwa kutulutsa kumakhala kotsika kuposa kumapeto kwa chakudya chakuthupi kotero kuti zinthu zimadutsa mu chowumitsira mothandizidwa ndi mphamvu yokoka.Zida zouma zimalowa mu chowumitsira ndipo, pamene chowumitsira chimayenda, zinthuzo zimakwezedwa ndi zipsepse zingapo (zomwe zimadziwika kuti ndege) zomwe zimayika khoma lamkati la chowumitsira.Zinthu zikafika pamtunda wokwanira, zimagwera pansi mpaka pansi pa chowumitsira, ndikudutsa mumtsinje wa gasi wotentha pamene ukugwa.
Chowumitsira chozungulira chitha kugawidwa kukhala chowumitsira ng'oma imodzi, chowumitsira ng'oma zitatu, chowumitsa ng'oma, chowumitsira paddle blade, chowumitsira mpweya, chowumitsira chitoliro chosalunjika, chowumitsira mafoni, ndi zina zambiri.
Mapulogalamu
Ma Rotary Dryers ali ndi ntchito zambiri koma amapezeka kwambiri m'mafakitale owumitsa mchenga, miyala, nthaka, ndi miyala.Amagwiritsidwanso ntchito m'mafakitale azakudya popanga zinthu zazing'ono monga mbewu, chimanga, phala, ndi nyemba za khofi.
Kupanga
Mapangidwe osiyanasiyana owumitsira ozungulira amapezeka kuti agwiritse ntchito mosiyanasiyana.Kuyenda kwa gasi, gwero la kutentha, ndi kapangidwe ka ng'oma zonse zimakhudza magwiridwe antchito komanso kukwanira kwa chowumitsira zinthu zosiyanasiyana.
Kuyenda kwa Gasi
Mtsinje wa mpweya wotentha ukhoza kusunthira kumapeto kwa chakudya kuchokera kumapeto kwa chakudya (chotchedwa co-current flow), kapena kumapeto kwa chakudya kuchokera kumapeto (kotchedwa counter-current flow).Momwe gasi amayendera limodzi ndi kutengera kwa ng'oma zimatsimikizira momwe zinthu zimayendera mwachangu powumitsa.
Gwero la Kutentha
Mtsinje wa gasi umatenthedwa kwambiri ndi chowotcha pogwiritsa ntchito gasi, malasha kapena mafuta.Ngati mpweya wotentha wa gasi umapangidwa ndi kusakaniza kwa mpweya ndi mpweya woyaka kuchokera ku chowotcha, chowumitsira chimadziwika kuti "chiwotcha mwachindunji".Kapenanso, mtsinje wa gasi ukhoza kukhala ndi mpweya kapena wina (nthawi zina inert) mpweya womwe umatenthedwa.Kumene mpweya woyaka moto sulowa mu chowumitsira, chowumitsiracho chimadziwika kuti "chotenthetsera mwachindunji".Nthawi zambiri, zowumitsira zowotchera mosadziwika bwino zimagwiritsidwa ntchito ngati vuto la kuipitsidwa kwazinthu.Nthawi zina, kuphatikiza zowumitsira zowotchera molunjika-zachindunji zimagwiritsidwanso ntchito kuti ziwongolere bwino.
Drum Design
Chowumitsira chozungulira chimatha kukhala ndi chipolopolo chimodzi kapena zipolopolo zingapo zokhazikika, ngakhale zipolopolo zopitilira zitatu sizifunikira.Ng'oma zambiri zimatha kuchepetsa kuchuluka kwa malo omwe zida zimafunikira kuti zikwaniritse zomwezo.Zowumitsira ng'oma zambiri nthawi zambiri zimatenthedwa mwachindunji ndi mafuta kapena gasi.Kuphatikiza kwa chipinda choyatsira kumapeto kwa chakudya kumathandizira kuti mafuta azigwiritsidwa ntchito moyenera, komanso kutentha kwa mpweya wofanana.
Njira Zophatikiza
Zowumitsira zina zozungulira zimatha kuphatikiza njira zina ndi kuyanika.Njira zina zomwe zingaphatikizidwe ndi kuyanika ndi kuziziritsa, kuyeretsa, kudula ndi kulekanitsa.
