在铁矿球团中,膨润土粘结剂降低了品位,增加操作费用。消耗率是膨润土质量、矿物学、操作水份和工艺设计的函数。本文评述了引起膨润土质量变化的各种因素,并阐述了与质量评定有关的工艺条件。一般性检验作了有用的评论,数据是从观察膨润土的到货、质量改良剂的效果和从膨润土中去除脉石的的变化中得到的。在球团操作上,关于影响膨润土质量的一些未来倾向也作了讨论。
In iron ore pellets, bentonite binders reduce grade and increase operating costs. Consumption rate is a function of bentonite quality, mineralogy, operational moisture and process design. This paper reviews the various factors that cause the quality of bentonite to vary and expounds the process conditions related to quality assessment. A useful review was made of the general tests, which were obtained from observations of the arrival of bentonite, the effects of quality improvers, and changes in gangue removed from bentonite. In the pellet operation, some future tendencies affecting the quality of bentonite are also discussed.
