The most common Hosokawa air classifier used for quartz is the Hosokawa Alpine Stratoplex (ASP) which is used for a cut point (top size) of 20 to 200 microns. For superfine applications, the Hosokawa Alpine Turboplex (ATP) air classifier is used, with a cut point (top size) of 5 to 50 microns, with single and multiwheel options.

In each experiment, kg of silica sand were fed into the machine. Another variable of interest that could affect the milling process is the milling ball size. In this category, two sizes of steel balls 18 and 16 mm have been chosen to be the grinding medium. Varying the rotational speed also affected the output grain size.

washed before being ball milled for a period of tim e. Then silica sand is separated, filtered, and ovendried. What is somewhat unique is that prior to being separated the sand is sedimented in a reactor. The next step is ball milling for the seco nd time to allow dispersion followed by sieving to obtain the nano size particles or nanosilica.
