Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

Smelting, Gresik, East Java, Indonesia. The manganese ore was obtained from East Nusa Tenggara Province, Indonesia. The slag was ground using a ball mill, sieved to obtain grain size of less than 65 mesh (210 µm), and then dried at 135 °C for 24 h. The manganese ore and bituminous coal were also ground and dried using the same procedures.

Ball grinding process is a grinding method of crushing ore with ballshaped grinding medium in the grinding mill. In the ball grinding process, because the steel ball has 360° free rotation, it is suitable for falling motion and throwing motion. When the rotating speed of the cylinder is low, the medium rises to a certain height along the ...
