Application of Nano-composite Ceramic Balls in High-silicon Refractory Iron Ore of Zhangzhuang Mine
In order to verify the feasibility of applying nano-composite ceramic balls to high-silicon and high-hardness iron ore,taking the second-stage ball milling feed of Masteel Zhangzhuang Mine as the raw material,the ratio test of different grain size ceramic balls,the test of all ceramic balls and ceramic balls + steel balls,the test of ball mill concentration and filling rate were carried out.The experimental re-sults show that under the condition of ceramic ballϕ30 mm、ϕ25 mm、ϕ20 mm ratio of 20%∶60%∶20%,fill-ing rate of 40%and ball milling concentration of 70%,the content of-0.023 mm in the particle size distribu-tion of ceramic ball and ceramic ball + steel ball milling products decreases by 31.98%and 21.29%,respec-tively.The particle size distribution of ceramic balls or ceramic balls + steel ball milling products under labo-ratory conditions can effectively reduce the generation of over-abrasive particles and reduce the power con-sumption of ball mills.Ceramic balls can be used instead of steel balls for industrial production.
