Lithium Mica Milling to 200mesh: Key Technology for Lithium Extraction and Equipment Application
Lithium mica is an important lithium-bearing mineral resource, which is an important raw material for the production of lithium carbonate, lithium hydroxide and other lithium products. With the rapid development of the new energy vehicle industry, the demand for lithium resources is increasing, and the development and utilization of lithium mica has attracted more and more attention. The milling of lithium mica to 200mesh is a key pre-treatment process for lithium extraction, which can improve the contact area between lithium mica and leaching agent, accelerate the leaching reaction and improve the lithium extraction rate.
When selecting milling equipment for lithium mica to 200mesh, the characteristics of lithium mica should be considered. Lithium mica has the characteristics of lamellar structure, low hardness and easy to grind. Therefore, the milling equipment should have good grinding effect and avoid damaging the lamellar structure of lithium mica as much as possible. At present, the commonly used equipment for lithium mica milling to 200mesh includes Raymond mill, vertical roller mill and ultra-fine ball mill.
Raymond mill is widely used in small-scale lithium mica milling projects due to its simple structure, easy operation and low investment cost. The Raymond mill can grind lithium mica to 200mesh, and the product quality is stable. However, its production efficiency is low, and it is not suitable for large-scale lithium mica processing projects. Vertical roller mill is a new type of efficient milling equipment, which is suitable for large-scale lithium mica milling. The vertical roller mill adopts the working principle of roller pressing and grinding, which can complete the processes of crushing, grinding, grading and conveying in one step. It has the advantages of high production efficiency, low energy consumption and good environmental protection performance. When milling lithium mica to 200mesh, the vertical roller mill can achieve a production capacity of 10-80 tons per hour, and the unit energy consumption is only 25-35 kWh/ton. Ultra-fine ball mill is suitable for the production of high-purity lithium mica powder. It can grind lithium mica to 200mesh or finer, and the product has high purity. However, its energy consumption is high, and the production cost is relatively high.
