SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.
