利用水力旋流器对广西典型钙基膨润土的湿法提纯研究
Study on Wet-way Purification of Guangxi Typical Ca-bentonite by Hydrocyclone
摘要
Abstract
In this paper,the typical Ca-bentonite of Guangxi was purified by using hydrocyclone,the influence of feed concentration,feed pressure and apex diameter on the purification of bentonite has been studied.The results showed that there was interaction among feed concentration,feed presure and apex diameter.In this experiment,the optimum conditions for purifying the Ca-bentonite were as that feed concentration,apex diameter and feed pressure were 15％,6mm and 0.35 MPa respectively.The performance indexes of bentonite had been improved after purified such as that the content of montmorillonite was increased from 62.50％ to 80.03％,the cation exchange capacity was increased from 41.87 mmol/100 g to 76.63 mmol/100 g and the colloid index was increased from 46.50 mL/15 g to 60.0 mL/15 g.关键词
