摘要
山西某铜矿选矿厂碎矿系统能力偏低,与球磨机需求不匹配,导致生产组织困难。经过试验研究,确定预先筛分上层筛孔50 mm×70 mm、下层筛孔12 mm×25 mm;检查筛分上层筛孔20 mm×35 mm、下层筛孔12 mm×25 mm;中碎破碎机排矿间隙31~33 mm;细碎破碎机排矿间隙11~13 mm。同时采用了新型高弹筛板,提高筛分效率。日常管理中,加强设备维护保养,合理组织生产,保证破碎系统高效稳定运行。
The capacity of crushing system in a copper concentrator in Shanxi is low,which does not match the demand of ball mill,resulting in difficulties in production organization.After test study,it is determined that for prescreening,the upper screen mesh is 50 mm×70 mm and the lower screen mesh is 12 mm×25 mm;for check screening,the upper screen mesh is 20 mm×35 mm and the lower screen mesh is 12 mm×25 mm;the ore discharge spacing of secondary crusher is 31~33 mm,and that of terti-ary crusher is 11~13 mm.At the same time,a new type of high-elastic screen plate is adopted to im-prove the screening efficiency.In daily management,it is necessary to strengthen equipment maintenance and organize production reasonably so as to ensure efficient and stable operation of crushing system.
