| Abstract: |
| In the course of ultrafine grinding of kaolin,the mechanical power leads crystal structure of kaolin to damage and the bond to breakage.The bond damage has occurred with mechanical force.This change makes chemisorption occur on the surface of particles of kaolin besides physical adsorption.It decreases external stress required by crushing particles and raises the grinding efficiency. |
