煤系高岭石生产超微细煅烧高岭土的工艺比较

COMPARISON OF PROCESSES OF PRODUCING SUPER FINE CALCINED KAOLIN BY UTILIZING COAL SERIES KAOLINITE

煤系高岭石生产涂布级煅烧高岭土的生产工艺， 主要包括煅烧增白和超细粉碎两个过程． 根据这两个过程先后顺序的排列以及超细粉碎工艺 （干法或湿法） 的选择， 分别组合成四种生产工艺． 文中分别论述了四种工艺的特点， 并筛选出“先湿法超细， 再煅烧增白”的工艺，

The process of producing super fine calcined kaolin was devided into two procedurs:super fine grinding and calcination. There are two super fine grinding methods, wet grinding and dry grinding. Four kinds of process were set up according to the sequence of two procedures and the choice of grinding methods. “wet grinding calcination” process was picked out as an optimizing one, after analyzing the characteristics of the four processes.\;
