The fly ash activation through mechanical milling is ussualy applied to improve the ash properties in order to get composite materials with higher characteristics. The activation technology based on mechanical energy action applied on treated materials and is conducted by ultra-fine milling. In order to increase the reactivity of lignite coal fly ash this paper focuses on optimization of mechanical activation period. Also, the influence of the ash activation parameters on the grain-size distribution related characteristics was studied during this research. The ash grain inertia measurement through automatic grain counter (AGC) was performed. Due this mechanically activated grains are the most convenient mineral form for measurement of grain inertia since energy change that occurs in the mill material system is recorded by them. The ash grains energy and properties could be changed by mechanical forces. The ash was thoroughly analyzed, particularly in its activated state, primarily by m...eans of the X-ray diffraction method for a reliable identification of the crystal phases and changes in the crystallinity, followed by comparison of the SEM microphotographs of its initial and activated state.
