Investigations on Fine Grinding of Mullite Ⅰ．The Effects of Processing Parameters on Size and Distributions of Mullite Powders in Attrtor

The effects of several processing parame-ters on size and distributions of mullite powders were studied in wet grinding with an attrition mill.The results show that there is an optimum initial slurry density,and also it has little rela-tionship with the media charge ratio.The size distributions of processed mullite are dependent on the grinding time and indepentdent of initial pulp density,Under given conditions,the larger the media charge ration is ,the finer the ground particle size will be.
