摘　　要：顽石是影响半自磨机处理能力的关键因素之一。为打通云南某多金属选矿厂影响产能提升的瓶颈,本文对半自磨机产出的顽石进行了针对性研究,依次开展了顽石性质研究、顽石开路-闭路工艺流程工业试验研究及JKSimMet软件流程模拟研究,分析了顽石在开路不返回、直接闭路返回和破碎闭路返回三种不同处理方式下对系统产能的影响。研究表明顽石在直接闭路返回条件下半自磨系统处理能力可达到400 t/h,顽石破碎闭路返回条件下半自磨系统处理能力预计可达到425 t/h,研究结果为选矿厂产能提升规模及技术改造方案提供了科学依据。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 400 t/h under the condition of direct closed return of pebble, and the processing capacity of the SAG system is expected to reach 425 t/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.
