摘要
锂云母是重要的锂资源之一,其提锂过程涉及多个工序环节,其中磨粉工序对后续锂浸出率及整体生产成本具有显著影响。本文分析比较了干式球磨、湿式球磨、立磨和广义盘磨等磨粉工艺设备的技术特性,包括处理能力、粒度控制、用电成本等关键参数。结果表明,广义盘磨电耗最低,但是磨粉粒径最粗,对后续锂浸出率有不利影响,适宜于对浸出过滤粒径要求不高的锂云母提锂工艺。湿式球磨机在节能和高效方面表现较为突出,而干式球磨机虽然处理量大,但能耗相对较高。立磨机电耗最高,但是磨粉粒径最细,且出料的粒径分布均匀,对后续锂的浸出率提高有一定作用,适宜于对浸出过滤粒径要求较高的锂云母提锂工艺。本研究可为锂云母提锂实际生产中磨粉工艺设备的合理选型提供参考。
Lithium mica is one of the important lithium resources,and its lithium extraction process involves multiple processes.Among them,the grinding process has a significant impact on the subsequent lithium leaching rate and the overall production cost.This paper analyzed and compared the technical characteristics of milling process equipment such as dry ball milling,wet ball milling,vertical mill and generalized disc grinding,including key parameters such as processing capacity,particle size control,and electricity cost.The results show that the power consumption of the generalized disc mill is the lowest,but the particle size of the mill powder is the coarsest,which has an adverse effect on the subsequent lithium leaching rate.It is suitable for the process of extracting lithium from lepidolite with low requirement for leaching filter particle size.The wet ball mill is more prominent in energy saving and high efficiency,while the dry ball mill has a large processing capacity,but the energy consumption is relatively high.The vertical mill has the highest power consumption,but the particle size of the mill powder is the smallest,and the particle size distribution of the discharged material is uniform,which has a certain effect on the improvement of the subsequent lithium leaching rate.It is suitable for the process of extracting lithium from lepidolite with high requirements for leaching filter particle size.The research in this paper can provide reference for the reasonable selection of grinding process equipment in the actual production of lithium mica lithium extraction.
