8.3.2.2 Ball mills. The ball mill is atumbling mill that uses steel balls as the grinding media. The length of thecylindrical shellisusually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
The High Energy BallMill E maxandMM 500were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.
Ball millsgive a controlled final grind and produce flotation feed of a uniformsize.Ball millstumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed toball mills(dry basis) is typically 75 vol.-% ore and 25% steel.

The size of the balls depends upon the size of the drum, typical ball sizes are two to three inches in diameter (four-inch balls are also possible). Bearings - smaller ball mills use anti-friction cylindrical roller bearings. Larger ball mills use trunnion bearings.
The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm. 6. Running Cost. The power consumption of the ball mill is slightly higher than that of the rod mill, and the wear rate is also higher than that of the rod mill.
