— Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

— Once they overheat and stop working, they won't work again. Use short 5-10 second pulses, shake the mill while you grind, and let the mill cool down before milling any more. WARNING: Do not confuse a blade-type coffee mill with a ball mill. The two types of mills work very differently. NEVER mill mixed chemicals together in a blade mill.

— This water is one- of the main controls that you have over your grind. Like many things it has its good sides and it's had sides. The good side is that it disperses the ore allowing contact between the rods and the ore to be uniform. It also maintains an even steady flow of material through the mill.
