FA usually comprises fine particles and a high amount of amorphous silica and alumina; therefore, it is used as a raw material to produce geopolymers [15,16]. High strength geopolymers are produced based on a class F FA [17,18]. To obtain alumina and silica precursors, FA should be mixed with an alkali solution [19,20].

Ball mill is the most common quartz grinding mill. The media balls inside the ball mill can ground quartz to fine powder. And the fineness can be controlled by the speed of the ball mill, the sizes and quantity of ball media. To obtain ultra fine quartz powder, the quartz grinding ball mill should work with primary and even secondary classifiers.
