HZG mndandanda rotary ng'oma (mkulu/kutsika kutentha) choumitsira
Ntchito
Zonyowa zakuthupi kuchokera ku chowumitsira zimayikidwa kumapeto kwa mkati mwa silinda ya nsalu kopi yotembenuza mbale, kugawa kofanana kwa zinthu mu chowumitsira ndi kubalalitsidwa, ndi kukhudzana ndi kutuluka kwathunthu (kutsutsa) mpweya wotentha, kufulumizitsa kuyanika misa Kutentha, kufalikira ku mphamvu yoyendetsa.Panthawi yowumitsa, zinthuzo zikhoza kuyendetsedwa kuti zisunthire ku valavu ina yotulutsa nyenyezi ya chowumitsira kuti itulutse mankhwalawo pansi pa zochitika za mbale yopendekera ndi kutuluka kwa mpweya wotentha.
Sinthani Kuzinthu
◎ mankhwala, migodi, zitsulo ndi mafakitale ena particles lalikulu, zinthu youma kuposa zazikulu, monga: migodi, kuphulika ng'anjo slag, malasha, zitsulo ufa, mankwala feteleza, ammonium sulphate.
◎Kuyanika ufa ndi zida za granular ndi zofunika zapadera, monga: HP thovu wothandizila, mbewu distiller a, kuwala kashiamu carbonate, adamulowetsa dongo, maginito ufa, graphite, ndi dregs.
◎ Pamafunika kuyanika kwa kutentha pang'ono, ndi magulu akuluakulu a zowumitsa mosalekeza.
Makhalidwe Antchito
◎ Choumitsira chozungulira chimakhala ndi makina ambiri komanso mphamvu zambiri zopangira.
◎ Kukaniza kwamadzimadzi kudzera mu silinda ndi yaying'ono ndipo kugwiritsa ntchito kwake kumakhala kochepa.
◎ Kusinthasintha kwa zinthu zakuthupi kumakhala kolimba.
◎ Kugwira ntchito mokhazikika, mtengo wotsika, komanso kuyanika bwino kwazinthu.
