It has been estimated that roughly ninety per cent of quartz bearing minerals were crushed by stamp mills. By 1875, California's Gold Rush country had nearly 400 mills operating. ... Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps. By the 1930s ...

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.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

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 ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.
