廻轉窑是我厂处理鋅浸出渣、鉛鼓风炉水淬渣及高鋅鉛粒的主要設备,其产品为氧化鋅——返回鋅系統回收鋅等有价金属;窑渣中含銅1.0—2.5％,送往銅系統回收銅。鋅浸出渣的化学成分如下(%): 鋅17—20、鉛2.0—3.5、銅0.9—2.0、硫7—8、鉄14—20、砷0.4—0.5、 銻1.0—7.0、氧化鈣5. 0—7.0、氧化鎂2.0—3.0、二氧化硅11—16,三氧化二鋁1.0—2.0。 廻轉窑窑身长32米,內径1.9米,容积90.7米~3。从窑头开始(2/3)-(3/4)处衬以高鋁砖,其余用普通耐火砖砌筑。
迴 Rotary kiln is the main equipment for zinc leaching residue, lead blast furnace water quenching residue and high zinc lead particles in our factory. The products are zinc oxide - return zinc system to recover zinc and other valuable metals; kiln slag contains copper 1.0- 2.5%, sent to the copper recovery copper. The chemical composition of the zinc leaching residue is as follows (%): zinc 17-20, lead 2.0-3.5, copper 0.9-2.0, sulfur 7-8, gallium 14-20, arsenic 0.4-0.5, antimony 1.0-7.0, calcium oxide 5. 0-7.0, magnesia 2.0-3.0, silica 11-16, alumina 1.0-2.0.迴 kiln kiln body length 32 meters, 1.9 meters in diameter, volume 90.7 meters ~ 3. Starting from the kiln head (2/3) - (3/4) lined with high alumina bricks, the rest of ordinary refractory brick masonry.
