摘　　要：以程潮铁矿为原料进行试验,考察了润磨时间和水分对原料性质和生球质量的影响,以及润磨工艺对膨润土配比和造球时间的影响。试验表明,润磨能细化混合料粒度,提高混合料比表面积,提高生球质量,降低膨润土用量,缩短造球时间。It makes test on Chengchao Iron Ore which is the raw material,inspecting the time of damp milling and the influence of moisture to the property of raw material and quality of green ball,also investigating the influence of damp milling technology to the proportion of bentonite and pelletizing time.The results shows that the damp milling can refine the particle size of mixed materials, increase the specific surface area of mixed materials, improve the quality of the green ball, and decrease the dosage of bentonite and pelletizing time.
