Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...

HPGR: HPGRs are generally more energyefficient compared to ball mills, especially in fine and ultrafine grinding applications. The highpressure grinding process consumes less energy per ton of ore processed, leading to lower operating costs. Ball Mill: Ball mills are widely used but can be less energyefficient, particularly when grinding ...

The tumbling reservoir of a ball, tube, roller, media, or vertical mill uses the impact and friction of the feed material, often supplemented by the action of stone or metal shapes. Hammer and impactor pulverizers use large hydraulic steel plungers or dropdown arms, either repeatedly or with stead force. Some use cages or chains instead.

For a rod millball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less ( from a closed circuit crusher) do not apply a rod mill efficiency factor.
