Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

In this stage, the grinding processes are typically carried out in horizontal tumbling mills, such as ball mills, rod mills and semi-autogenous grinding (SAG) mills (Francioli, 2015). These mills are differentiated by the media employed in the grinding process as well as by the diameter/length relationship.

Semi-autogenous mills (SAG mills) can accomplish the same size reduction work as two or three stages of crushing and screening. ... a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible.

Grinding media can be the ore itself (autogenous grinding -- primary and secondary), natural or manufactured non-metallic media (pebble milling) or manufactured metallic media -- steel rods, steel or iron balls.
