With the rapid development of the new energy industry, lithium extraction has become a research hotspot in various fields. In the aluminum electrolyte process, because the lithium contained in low-grade bauxite (equivalent to li2o3 0.58%) is continuously enriched in the electrolytic tank along with the alumina raw materials, the lithium content in the electrolyte gradually increases. Therefore, many aluminum plants choose to grind and pretreat electrolytic aluminum slag and sell it to downstream lithium extraction companies to create economic value. So, what kind of mill is best for grinding electrolytic aluminum slag? As a manufacturer of aluminum slag grinding machines, Guilin Hongcheng will provide you with analysis and answers today.
To extract lithium from electrolytic aluminum slag, the waste residue must first be dried to reduce its moisture content to less than 5%. Then, it is pulverized by an aluminum slag mill to obtain powder with a particle size of less than 100 mesh, which provides better conditions for subsequent acid leaching. What kind of mill is best for grinding electrolytic aluminum slag? In terms of equipment selection, both longitudinal pendulum mills and vertical mills can meet the requirements. In contrast, vertical mills have high production efficiency and are suitable for medium and large-scale milling projects, but the investment is also high. The large, longitudinal swing mill is an upgraded version of the Raymond mill, which is more economical and practical. Therefore, longitudinal pendulum mills are also widely used in electrolytic aluminum slag grinding production. Compared with the traditional Raymond mill, the performance of the longitudinal pendulum mill has been greatly improved after several generations of technical transformation of the mill, whether in terms of output, product quality, or impact on the environment, and Intelligent operation and cost control can meet the requirements of a modern powder factory.
The HC series longitudinal pendulum mill produced by Guilin Hongcheng is the leader among pendulum mills and has been successfully applied and recognized in the production of electrolytic aluminum slag grinding.
