Mills Grinding Generally ball mills are more common than Rod mills or Sag Mills, there are other types of mills available such as Vertical mills but the last three mentioned are by far the most common. Ball and mills use steel balls or ceramic balls as their grinding media. Rods mills as the name suggest use rods as their grinding media. The larger mills are a continuous process which means ...

Often an existing plant that observes their SAG mill is limiting throughput, but the ball mills are underloaded can opencircuit the primary mill to better balance the grinding load with the secondary mill.

Principle of SAG Mill operation. SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%.[6][7] The largest SAG mill is 42′ () in diameter, powered by a 28 MW (38,000 HP ...

The SAG mill was installed with a low ball charge, no variable speed and a fine grind was targeted (P80 106 µm). High circulating loads and difficulty achieving the target grind size were experienced. This type of ore should have been treated in a high ball charge SAG mill with variable speed capability.
