    If the build-up of critical sized pebbles is too great 50–90 mm slots are cut into the grate (pebble ports) to allow the scats to discharge from the mill. These scats are crushed before returning to the SAG mill or passing onto a ball mill in an autogenous/ball mill/crusher (ABC) circuit (Figures 9.3 and 9.6).

  • Crusher Wikipedia

    Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.
