Abstract A comparative testwork programme was conducted using a laboratory scale vertical fluidised stirred media mill. The mill was operated with and without the presence of a disc liner on the shell. Results showed that when the mill was operating with pin and disc type stirrers, the addition of a stationary liner to the mill shell significantly increased the mill power draw. In grinding experiments conducted with silica, it was found that the production rate was enhanced as a result of the higher power draw. No detrimental effect on the grinding energy efficiency was observed. It was postulated that the addition of the disc liner increased the stress intensity of the milling operation. The results of this study show that the addition of stationary internal disc liners have a potential to increase the production capacity of fluidised stirred media mills. Further work is recommended to confirm that these observations are valid at a larger scale and in continuous milling configuration.

研究向立式流化搅拌介质磨机添加壳衬时对功率消耗和研磨性能的影响

摘要 使用实验室规模的立式流化搅拌介质磨机进行了对比测试工作。磨机在外壳上有和没有盘衬里的情况下运行。结果表明，当磨机使用销式和圆盘式搅拌器运行时，在磨机外壳上增加一个固定衬板显着增加了磨机功率消耗。在用二氧化硅进行的研磨实验中，发现由于更高的功率消耗而提高了生产率。没有观察到对研磨能量效率的不利影响。据推测，圆盘衬垫的添加增加了铣削操作的应力强度。这项研究的结果表明，添加固定内部圆盘衬板有可能提高流化搅拌介质磨的生产能力。建议进一步工作以确认这些观察结果在更大规模和连续铣削配置中有效。
