摘　　要：随着硫酸法钛白粉市场对还原铁粉需求的增加,现有工艺无法满足要求,为此开展粗粒级铁粉(>40目)的深度破解实验,采用湿法大型球磨机多级研磨及2ZM-200和2ZM-400型振动棒磨机分别开展破碎试验。试验结果表明:采用球磨机多级研磨后破碎率为32.16%,而采用振动棒磨机并控制下料速度后,破碎率最高58.15%(料速1~3kg/min),铁粉产品满足工艺要求。Due to continuous improving requirements for iron powder used for sulfuric acid method titanium dioxide reduction,existing process can not meet the product requirement.Therefore,this study carries out the deep cracking experiment on coarse-grain iron powder(>40 mesh)and the crushing tests by wet method multi-stage grinding by using large-scale ball grinder and 2ZM-200 and 2ZM-400 type vibrating rod mills.The results show that the crushing rate of multi-stage grinding by the ball grinder is 32.16%,while the crushing rate of the vibrating rod mill combining with charging speed control can reach as high as 58.15%(charging speed:1~3 kg/min),and thus the product iron power can meet the process requirements.
