I-PRETREATMENT DRUM & HEATING ucezu lwesisetshenziswa esisetshenziswa ekukhiqizeni izimboni ukuze kulungiswe kuqala izinto ezingavuthiwe. Ngokuvamile iqukethe umgqomo ojikelezayo wokwelashwa kanye nesistimu yokushisisa. Ngesikhathi sokusebenza, izinto zokusetshenziswa zifakwa emgqonyeni ojikelezayo wokwelashwa wangaphambi kokwelashwa futhi zishiswe yisistimu yokushisa. Lokhu kusiza ukuguqula izakhiwo ezingokomzimba noma zamakhemikhali zempahla eluhlaza, okwenza kube lula ukuyiphatha ngesikhathi sezinqubo zokukhiqiza ezilandelayo. Lolu hlobo lwemishini luvamise ukusetshenziswa embonini yamakhemikhali, ekucutshungulweni kokudla, ezamakhemisi nakwezinye izimboni ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.
