Abstract

In this paper. the peculiar phenomenon of counter-grinding" in the superfinegrinding process is revealed. based on studying the powdery quartz. This phenomenon is described and analyzed in detail on the basis of a lot of experimental data.It may provide the basis for selecting the rational process conditions, effective control of the grinding limit and delaying the grinding equilbrium in the superfine grinding process.It is of the theoretical significance and practical value for the developmentof powder technology.

Keywords：powdery quartz: superfine-grinding;granulation
