碳酸化球团是一种投资少,工艺设备简单,成本低,使用效果较好的造块方法。其主要工艺流程为:配料→球磨→造球→碳酸化固结(见图1)。我厂碳酸化球矿的生产开始于1963年,以前粉矿的处理,我们曾采用过各种烧结造块和生球焙烧固结的方法。但是,由于在生产中提高成品率与降低Feo含量的矛盾始终难以解决,后来便停止了生产,转而采用碳酸化球团的方法。今后将继续改进其工艺流程,并扩大生产。
Carbonated pellets is a less investment, process equipment is simple, low cost, the use of better block method. The main process is: ingredients → ball mill → ball → carbonated consolidation (see Figure 1). The production of carbonated ball mine in our factory began in 1963. Before the treatment of powder ore, we have used various methods of sintering and pelletizing. However, since the conflict between increasing the yield and reducing the Feo content in production has always been difficult to solve, production was stopped and carbonated pellets were used instead. In the future, it will continue to improve its technological process and expand its production.
