### Autogenous and Semi-Autogenous Mills - ScienceDirect

9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media.

### Rod Mill Feed Size - Grinding & Classification Circuits ...

Rod mills have become niche comminution devices since about 30 years ago. Because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling (a potentially deadly failure for those tasked with rectifying the problem) rod mills have a maximum installed power of about 2.5 MW.

### Effects of mill feed size and rod charges on grinding ...

The effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.
