Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is8.53 m diameterand13.41 m longwith a corresponding motor power of 22 MW (Toromocho, private communications)
Theball millaccepts the SAG or AGmill product.Ball millsgive a controlled final grind and produce flotation feed of a uniformsize.Ball millstumble iron or steelballswith the ore. Theballsare initially 5–10 cm diameter but gradually wear away asgrindingof the ore proceeds

Theball millis a tumblingmillthat uses steelballsas thegrindingmedia. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimizeballcoating, or slurry containing 20–40% water by weight
Apr 01, 2007· While stirred media mills have shown to be more energy efficient than ball mills for ultra-fine grinding (<25 μm product size), they still have limitations. One such limitation is the size of the mills available and hence the low throughput achievable (currently less than 100 tph)
Reliable and effectivegrindingtechnology for diverse applications. With more than 100 years of experience in developing this technology. Metso Outotec has designed, manufactured and installed over 8,000balland pebblemillsall over the world for a wide range of applications
The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm
PlanetaryBall Millsare used wherever the highest degree of fineness is required. Apart from the classical mixing andsizereduction processes, themillsalso meet all the technical requirements for colloidalgrindingand have the energy input necessary for mechanical alloying processes
According to [26], whengrindingin aball mill, the reduction insizeoccurs according to three mechanisms of fragmentation: abrasion, splitting, and destruction ( Figure 3). In comparison with
High Amplitude Wet or Dry Mills Vibratory Grinding Mills Size Reduction Equipment Specifically designed for wet or dry grinding, the high amplitude Vibro-Energy Grinding Mills range from 1 ft³ (36 liters) to 75 ft³ (1,934 liters) of volume. Wet or Dry Grinding Mill Models: DM1, DM4, DM10, DM20, DM28, DM70 Low Amplitude Wet Mills
A ball mill grinds ores to an end product size of thirty-five mesh or finer. • Primary crushing and autogenous/semi-autogenous grinding. • eighty percent of twenty-five millimeters or finer for fragile rocks (Larger feed sizes can be tolerated depending on the requirements)
They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
