Cone crushers are used in AG and SAG grinding circuits to increase tonnage by effectively dealing with any pebble (critical size) build-up problem. Normally, heavy duty short-head crushers are employed to crush pebbles. Power and crusher cavity level are the key variables for monitoring and controlling the crusher operation.
The physics of the bottom adjust cone are different than a top adjust cone as the maximum feed size remains constant throughout the life of the liner on the bottom adjust cone crusher. Feed size in top adjust cones shrinks as the liner wears automation. Both systems may have automation.
