叶腊石的生产工艺
作者:管理员    发布于:2016-09-24 09:18:12    文字:【】【】【

1、叶腊石的工艺流程并不固定,根据产品的需要而定,如用于耐火材料,制耐火砖的叶腊石,白度要求不高,产品粒度也不要求很细,粒度为3mm左右,通常为干法生产。用于耐火材料制砖用叶腊石工艺流程为:叶腊石原料--洗矿--颚式破碎机--辊式破碎机--产品

2、用于陶瓷、造纸、农药载体等的叶腊石,细度往往要求在200目以下,白度85%以上,这是流程中除粗、中、细碎外,还要悬辊粉碎机进行粉碎,这是多用湿法作业。用于陶瓷、造纸的叶腊石工艺流程为:叶腊石原料--洗矿--粗碎--中碎--细碎--磨碎--重选或浮选--分级(沉淀池或水力旋流器)--提纯(漂白)--过滤--干燥(自然干燥或链板干燥机)--微粉碎--产品
