### Autogenous and Semiautogenous mills

Simplifying wet grinding with AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.

This is important as if you have not seen if yourself, you can not trust it is really 10mm. There should be no scats at 10 mm unless you are using much too small a grinding ball or the mill charge is much too low. For example, I was told by a client his ball mill feed was P80 = 9mm but when I went to look at the feed belt, I saw this below.
