Application scope of JM stirred ball mill. 2.1, Adopting The vertical spiral stirred mill to grinding the gold ore, and the same time leaching operation, can extract gold economically with low cost and high gold recovery
al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 m
maintenance and down time, and maximize wear life - the Vertimill was born. In the twenty years ... fluidized stirred mills would be another option, but many operations don’t yet grind that fine with copper concentrate. ...
