2017年6月2日· Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft in diameter to small mills used for sample preparation in laboratories Rod mills are similar to ball mills and use metal rods as the grinding media Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles8322 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter (Figure 811 ) The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weightBall Mill an overview | ScienceDirect Topics
Performance optimization of an industrial ball mill for SciELO
The energy consumption in the ball mill was found to be 65 kWh/t of ore with a targeted product size below 1 mm The BWI of the ores varied from 58 to 78 kWh/t to reduce the particle size below 100 μ m, but in real time, the energy consumption is very high compared with the reported value of 65 kWh/tIf a ball mill uses little or no water during grinding, it is a ‘dry’ mill If a ball mill uses water during grinding, it is a ‘wet’ mill A typical ball mill will have a drum length that is 1 or 15 times the drum diameter Ball mills with a drum length to diameter ratio greater than 15 are referred to as tube millsBall Mill (Ball Mills Explained) saVRee saVRee
