WEBIn this section, we'll explore the main differences between SAG and AG mills, including their definition, operation, design, and appliions. SAG mills, or SemiAutogenous Grinding mills, use a combination of steel balls and rock particles to grind ore. They are larger in size and are capable of grinding larger quantities of ore than AG mills.
