Ball milling of fresh fly ash up to 60 h reduced its size by a magnitude of 405 times to 148 nm. The specific surface area has increased from 0.249 m 2 /gm for fresh fly ash to 25.53 m 2 /gm for fly ash ball milled up to 60 h. The increase in surface area has been found to be more than 100 times in magnitude. Figure 1
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.
