Abstract：In this paper. the peculiar phenomenon of "counter-grinding" in the superfine-grinding process is revealed. based on studying the powdery quartz.This phenomenon is describedand analyzed in detail on the basis of a lot of experimental data. It may provide the basis forselecting the rational process conditions，effective control of the grinding limit and delaying thegrinding equilibrium in the superfine grinding process. It is of the theoretical significance andpractical value for the development of powder technology.

Keywords：powdery quartz: superfine-grinding: granulation
