介绍磷矿含碳球团的生产工艺、操作控制指标、性能特征及应用情况。利用磷矿粉、焦炭、黏结剂等制成球团,在烧结立窑中950℃下烧制成球团熟料,并按一定的比例掺入磷矿中进行了钙镁磷肥工业生产试验,改善了炉况,降低了焦炭的消耗,开发利用了低品位磷矿资源。
The production process, operation control index, performance characteristics and application of phosphate rock pellets are introduced. Using phosphate rock powder, coke, binder made of pellets, fired in a sintering kiln at 950 ℃ into pellets clinker, and according to a certain percentage of phosphate rock in the calcium phosphate magnesium fertilizer industrial production test, Improved furnace conditions, reduced coke consumption, development and utilization of low grade phosphate rock resources.
