sizes. The results of these studies showed that a single line 40 ft SAG mill circuit gave the best project economics. Further work was followed up to optimize the 40 ft SAG mill size with the results showing that a slightly more expensive 42 ft SAG mill with equivalent power to the 40 ft SAG mill enhanced the project economics.

Grinding in Ball Mills: Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The

SAG Mill Ball Size Evaluator | Evaluation Factors | Calculate Diameter

SAG mills can operate with balls bigger than 4″, yes. But what job do you need these balls to do? It is difficult to generalize on SAG mill ball size selection as it depends on a number of factors some Finer feed (i.e. secondary crushed) justifies a 4″ ball but if the grate opening is 60 mm x 100 mm...
