粉石英超细粉碎过程中的“逆粉碎”现象

The Phenomenon of Counter-grinding in the Superfine-grinding Process

以大量实验数据和理论分析为基础揭示了超细粉碎过程中特有的“逆粉碎”现象，提出了“逆粉碎”不是一个点而是一个过程的新概念。为合理选择工艺条件、有效控制粉碎极限和延缓粉碎平衡、推迟“逆粉碎”的出现，提供了一定的参考依据，对推进粉体技术的发展具有一定的理论意义和实用价值。

The peculiar phenomenon of counter-grinding in the superfine-grinding process is revealed based on a lot of experimental data and theoretical analyses. A new concept is put forward that the phenomenon of counter-grinding is not a dot but a process.It may provide the basis for selecting the rational technology conditions.effective control of the grinding limit and delaying the grinding equilibrium. It has the theoretical significance and practical value for the development of powder technology.
