Noise Monitoring That Prevents Mill Damage | Brüel & Kjær
So now we are able to listen to any SAG or AG mill and measure the entire frequency spectrum live from a Type 2250, or a Type 2270, and pass the entire frequency spectrum directly into a control system with no computer. This makes the entire solution simple and elegant and very robust," explains John Karageorgos.

What's the difference of Ball mill, SAG mill, AG mill?
Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
