我们现以纯钠型和钙型蒙脱石作为粘结剂进行铁精矿造球的实验室试验研究为例,对添加剂在造球中的作用作概要的说明。这些研究的结果表明可以用已知的物理一化学概念来解释蒙脱石对生球成长速度和干球强度的影响。蒙脱石粘土片晶的聚集程度和这样的物料使水固定的能力对造球有强烈的影响,粘土的这些性能决定于粘土中可交换的阳离子的价数。 We are now pure sodium and calcium montmorillonite as binder for iron ore pelletizing laboratory test as an example, the role of additives in pelleting for a brief description. The results of these studies show that the known physical-chemical concept can be used to explain the effect of montmorillonite on the growth rate of green balls and the dry-bulb strength. The degree of aggregation of smectite clay platelets and the ability of such materials to fix water have a strong effect on pelleting, and these properties of clay depend on the valence of the exchangeable cations in the clay.
