Abstract:This article systematically studied the application of ceramic ball milling technology on the regrinding operation of copper sulfur mixed concentrate in large-scale beneficiation plant. By comparing and analyzing the particle size distribution and the grinding kinetic parameters of ceramic balls and traditional steel balls during the grinding process, the advantages of ceramic ball milling were revealed, and its industrial application prospects were discussed. The optimal conditions for ceramic ball milling were determined through single factor experiments: a ratio of 2∶6∶2 for ceramic balls with diameters of 30 mm, 25 mm, and 20 mm was established, with a slurry concentration of 70% and a filling rate of 40%. The results indicated that ceramic balls can replace steel balls and optimize the particle size distribution of grinding products. In industrial applications, ceramic ball milling improved the particle size distribution of overflow products. The Cu distribution rate of -0.01 mm particle size for ceramic ball milling was 13.1% lower than that for steel ball milling, with a reduction in power consumption of 50.28% and a reduction in unit ball consumption of 82.14%.
