can influence wet ball milling of quartz both beneficially and deterimentally, depending on pH and additive concentration. These resul~ are reproduced in Fig. 1. It can be seen that the amine addition to the ball mill is benefi-cial, except under acidic conditions, where detrimental effec~ are obtained at all amine levels.

3. Ball Mill. Load crushed quartz into the ball mill with steel balls. Add water to just cover the raw material to minimize dust. As quartz and steel balls tumble within the rotating mill, the steel balls pulverize the quartz into a fine powder. Grind quartz down to the optimal size such as 200 mesh or less for desired uses.
