Grinding mill is the core equipment of raw material preparation, which will directly affect the production efficiency and quality of cement. In current cement plants, the vertical roller mill grinding system, roller press grinding system, and ball mill grinding system are the most frequently used and most efficient grinding systems.

Fly ash is the main solid waste discharged from coal-fired power plants. Fly ash can be used as cement mixture after being processed by grinding equipment to improve the performance of concrete. With the development of industry, fly ash is used in more fields, and the fly ash vertical mill has gradually attracted people's attention.

Aydın et al. (2010) showed that grinding process of fly ash improved the mechanical properties of cement/fly ash mortar significantly. Furthermore the incorporation of fly ash with different fineness and ratios also decreased the expansions to harmless levels of cement mortars due to alkali–silica reaction.

The work reported herein focused on the effects of mechanical activation via ball-milling, and the environment of mill (air, N2, CO2) on the activity of coal fly ash as an aluminosilicate precursor in production of geopolymer (via alkali activation). N2 was selected as an inert environment where reactions with the mill environment would

Short and long-term compressive strength of concrete of Afşin-Elbistan type-C fly ash is analyzed at six different Blaine fineness values which are determined as 1834 cm 2 /g, 1852 cm 2 /g, 1930 cm 2 /g, 1962 cm 2 /g, 1995 cm 2 /g, and 2018 cm 2 /g, respectively. For this purpose, fly ash was ground from the ball mill for 0, 10, 20, 30, 45, and 60 min, and it was …
