黑山膨润土制备球团粘结剂研究

Study on Preparation of Pellet Binder Used Heishan Bentonite

通过XRD、SEM和化学分析等方法,对黑山膨润土性质进行了研究,对其进行了钠化,在钠化的基础上,对添加的有机药剂种类和用量进行了研究,确定添加羧甲基纤维素钠,用量为0.02%,制备的球团粘结剂在铁精矿粉中的添加量可以降低到1.5%。并对球团粘结剂中的有机药剂的作用机理进行了分析。

, The properties of Heishan bentonite were studied through the methods of XRD, SEM and chemical analysis. Carried on the sodium test. On the basis of the sodium, the kind and amount of added organic reagents were studied. Decided to add carboxymethyl cellulose, the dosage was 0.02%. The addition amount of pellet binder can be reduced to 1.5 % in iron ore concentrate. And the mechanisms of organic reagent in the pellet binder were analyzed.
