电气石湿法超细粉碎及分散机理研究

Study on Wet Superfine Pulverization and Dispersing Mechanics of Tour maline

在用湿法超细粉碎电气石的过程中,分散剂的加入不仅可缩短电气石的研磨时间,并且可防止料浆干燥后团聚。本研究以新疆电气石为原料,选择不同种类的分散剂,系统研究了分散剂在电气石超细粉碎过程中的作用效果与机理,总结了超细粉碎的最佳工艺条件,制备出粒径d97<3.0μm、d90<1.8μm、d50<0.5μm的电气石粉。

In the process of wet superfine pulverization of tourmaline, dispersant is necessary. It could shorten the grinding time and prevent the slurry agglomerating. In this article the raw material is Sinjiang tourmaline and the dispersants are different. The action effects and mechanics are studied systematically, the optical technological conditions are also generalized. The grain size of tourmaline powders is d97〈3.0μm, d90〈1.8μm, d50〈0.5μm.
