the pebble crusher feed bins via the pebble crusher feed conveyor. The -4mm material flows into the common mill discharge sump. 3.2.2 Pebble Crushing Circuit Pebbles from the secondary mill pebble feed bin are withdrawn at a controlled rate by a belt feeder and delivered to the secondary mill via a pebble transfer conveyor. The rate

SAG Mill Pebble Crushing Further size reduction of the pebble fraction in an SABC (semiautogenous ball crusher) circuit can be achieved by passing the pebble crusher product through an …

For tumbling mills the 2 indices relate to "coarse" and "fine" ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits. "Coarse" in this case is defined as spanning the size range from a P80 of 750

Autogenous mills(AG Mill)/ semiautogenous mills(SAG Mill) The CITIC autogenous / semiautogenous mills are utilized to grind run-of-mine rock or primary crusher discharge. The feed size to this mill is limited to the maximum size that can be practically conveyed and introduced into the mill.

In this circuit, two SAG mills have the same throughput, feed rate and the recycling load. Below all the simulation results are from SAG mill 1. The first graph shows that the throughput of the SAG mills is affected by the pebble crusher settings.

b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in.) is taken out through pebble ports for separate crushing and ball milling. The minus ½ in. fraction of mill discharge is recycled to the SAG mill through a classifier. The circuit is called SACB: Semi autogenous/ Crusher/Ball mill.
