Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible. In 1932, the world's first Φ7.3 m × 0.9 m ...
(4 to 14 mesh; or, finer) obtained from rod mills or from primary or intermediate autogenous mills. Grinding media in these mills are rock pebbles of suitable size (1-½" to 3-½") bled off from primary autogenous mills or screened out of intermediate crushing circuits. Primary Autogenous Mills

Grinding using a Ball Mill is an advanced process that aims to reduce the grain size of the material in order to obtain finer grain sizes (fine material) and prepare the right grain size for the ...
A comparison of the grinding media is given together with the knowledge gaps that still need to be bridged to improve the quality and performance of grinding media used in ball mills.
a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material ...
