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 50mm×70mm and the lower screen mesh is 12mm×25mm; for check screening, the upper screen mesh is 20mm×35mm and the lower screen mesh is 12mm×25mm; the ore discharge spacing of secondary crusher is 31~33mm, and that of tertiary crusher is 11~13mm. At the same time, a new type of high-elastic screen plate is adopted to improve 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.
