Gold plant pebble crushing | Henan Deya Machinery Co., Ltd.

Conventionally, crusher product was returned to SAG feed. Some designs, however, now allow pebble-crusher product to be returned to the SAG screens/discharge (allowing operation of the pebble crusher in closed circuit) or even to the ball-mill circuit. There is no 'right' answer for where the crusher product should be put of the time.

Trio TC51 Pebble Crusher Westgold Resources Bluebird ...

A Trio ® TC51 cone crusher along with a skid, including isolation frame, drive motor, ancillary lubrication and hydraulic systems was installed in Bluebird's mill circuit. With the new arrangement, the pebble load on the mill was decreased, thus increasing plant production by as much as 25% once the cone crusher was in operation.
