AG & SAG Mill for Mineral Processing Wet & Aerofall SAG ...

What is a SAG mill? The structure of the SAG mill (semi-automatic grinding mill) and the AG mill (autogenous grinding mill)are exactly the same, except that a certain proportion of auxiliary grinding media such as steel balls or steel rods are added as needed. During the process of the AG mill operation, some ores with diameters greater than 20mm but less than 80mm are not easily ground.

What's the Difference Between SAG Mill and Ball Mill ...
