The key technology of lithium mica milling to 200mesh is to control the fineness and particle size distribution of the powder. The fineness of the powder directly affects the lithium extraction rate. If the fineness is too coarse, the contact area between lithium mica and leaching agent is small, and the lithium extraction rate is low; if the fineness is too fine, the powder is easy to agglomerate, which also affects the leaching effect. Therefore, it is necessary to select milling equipment with high-precision grading system to ensure that the 200mesh qualified powder accounts for more than 90%. At the same time, the moisture content of the powder should be controlled below 3%, which can prevent the powder from agglomerating during storage and transportation.
In addition to the selection of milling equipment, the pre-treatment of lithium mica raw materials is also very important. The raw lithium mica often contains impurities such as quartz and feldspar. Before milling, it is necessary to separate the impurities through gravity separation or magnetic separation to improve the grade of lithium mica. This can not only improve the lithium extraction rate, but also reduce the wear of milling equipment.
The 200mesh lithium mica powder produced by milling is an important raw material for lithium extraction. After leaching, purification and other processes, it can produce high-purity lithium carbonate and lithium hydroxide, which are widely used in the production of lithium-ion batteries. With the continuous improvement of lithium extraction technology, the demand for 200mesh lithium mica powder will continue to increase. Therefore, the research and development of efficient and energy-saving lithium mica milling equipment is of great significance for promoting the development of the lithium mica industry.
