Pebble is one of the key factors affecting the processing capacity of SAG mill. In order to break through the bottleneck of a multi-metal concentrator in Yunnan Province, this paper carried out a targeted study on the SAG mill pebble, carried out the property study of pebble, the open-closed circuit test study of pebble and the simulation analysis study of JKSimMet software, and analyzed the influence of different treatment methods on the system productivity of pebble. The research shows that the processing capacity of the SAG system can reach 400t/h under the condition of direct closed return of pebble, and the processing capacity of the SAG system is expected to reach 425t/h under the condition of closed return of pebble crushing, It provides scientific basis for the capacity upgrading scale and technical transformation scheme of concentrator.
