摘 要：<正> As one of main raw materials in ceramic industry, chinastone mostly contains minerals such as quartz and sericite. In ultrafine processing of chinastone, the aggregation and adhesion of micropowders caused by surface effect lower the efficiency of ultrafine comminution. In this paper, a kind of grinding aid for chinastone delaminating has been developed by the author to change the surfacial electronic property of particles and decrease the viscosity of pulp. Experiments about delaminating-comminuting chinastone ores from Ningcun and Shangzhu （Jiangxi Province, China） reveal that the contents of 2 um grade particles are increased from 23. 0% and 27. 1% to 42. 7% and 45. 3% respectively, the products reach the index at first-class chinastone.
