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.
The TM 300 Drum Mill is utilized for preparing granules and powders through a grinding process conducted in either dry or wet conditions. This versatile grinder can function as either a Ball or a Rod Mill by employing the corresponding module. To ensure an efficient grinding process, it is essential to use a sufficient number of balls or rods.
