The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.

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.
