Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in ...

The Science of Comminution

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.
