铁矿石的使成粒状行为为随后的参数优化和有效使成粒状是必要的，特别在改变材料条件下面。在这研究，表面性质和粒子尺寸的效果用一个实验室使成粒状方法被分析；sintering 混合的使成粒状的一个评价随后为基础矿石被进行。而 wettability 断然影响了使成粒状并且是最有影响的因素，圆和孔被观察否定地影响铁矿石的使成粒状，显示铁矿石弄湿在使成粒状期间是合乎需要的。当有复杂尺寸分布的铁矿石被成粒时，相等的表面区域比 1 公里和到中介的粘住的罚款的比率是为比 1 公里小的好粒子的主要因素的是为大的粗糙的粒子的主要影响因素。由把粗糙、好的粒子的使成粒状与他们的分配相结合，我们为估计 sintering 混合的使成粒状能力建议了一个计算方法。好确认与设计计划被表明。结果建议发达方法为预言铁矿石混合物的使成粒状是有效的。

英文摘要：

The granulation behavior of iron ores is essential for subsequent parameter optimization and efficient granulation, especially under changing material conditions. In this study, the effects of surface properties and particle size were analyzed using a laboratory granulation method; an estimation of the granulation of sintering blends was subsequently conducted for the base ores. Circularity and porosity were observed to negatively affect the granulation of iron ores, whereas wettability positively affected the granulation and was the most influential factor, indicating that wetting of iron ores is desirable during granulation. When iron ores with complex size distributions were granulated, the equivalent surface area was the main influencing factor for coarse particles larger than 1 mm and the ratio of adhering fines to intermediates was the main factor for fine particles smaller than 1 mm. By combining the granulation of coarse and fine particles with their proportioning, we proposed a calculation method for estimating the granulation ability of sintering blends. Good verification was demonstrated with the designed schemes. The results suggest that the developed method is effective for predicting the granulation of iron ore mixtures.
