承钢链篦机—回转窑以煤为热源生产酸性球团,是当前国内自行设计、制造的一座生产球团矿的大型装置。目前利用系数达到3.785吨/米~3·日,日历作业率为80.92%;成品球团矿抗压强度2050.6牛顿/个球,转鼓指数(+5毫米)89.5%。初步显示了链篦机-回转窑球团生产工艺适应性强,容易操作,单机生产能力大和球团质量好等特点。文中对适宜的原料条件,链篦机的干燥和预热,以及回转窑内焙烧制鹰等进行了分析与讨论,并且提出了改进的技术措施。
Cheng Gang grate - rotary kiln to produce acid pellets heat source of coal, is the current domestic design, manufacture a large-scale production of pellet plant. The current utilization factor reached 3.785 t / m ~ 3 · day, and the calendar operating rate was 80.92%. The compressive strength of finished pellets was 2050.6 N / ball and the drum index (+5 mm) was 89.5%. Preliminary shows that grate - rotary kiln pellet production process adaptability, easy operation, stand-alone production capacity and pellet quality is good and so on. In this paper, the suitable raw material conditions, the grate drying and preheating, as well as the rotary kiln roasted Eagle were analyzed and discussed, and put forward improved technical measures.
