    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.
