The extraction process of lithium carbonate, a key material for the positive electrode of lithium batteries, is divided into two categories: ore extraction and salt lake brine extraction. In terms of ore extraction, lithium-containing ores in nature mainly include spodumene, lepidolite, and petalite. Among them, spodumene has a high lithium content and is the most important lithium mineral resource. For the new energy lithium battery industry chain, whether it is lithium salt, cobalt salt, nickel salt or manganese-based materials, the raw materials need to be ground to a certain fineness to meet the needs of the next step of roasting or leaching.

As a provider of overall solutions for large-scale grinding equipment, Liming Heavy Industry has launched the LM vertical roller mill for the preparation of key materials in the new energy industry. It has been widely used in ore grinding, roasting material grinding and fuel coal powder preparation processes. It is not only energy-saving and high-output, but also intelligent and environmentally friendly.

LM series vertical roller mill, also known as vertical mill, is a large-scale high-efficiency and energy-saving grinding product developed by Liming Heavy Industry with comprehensive introduction of superior technologies from Germany's Loesche and Feifan, combined with our company's more than 30 years of R&D and manufacturing experience. It integrates grinding, drying and powder selection, and has a number of independent patent technologies and intellectual property rights. The main technical and economic indicators have reached the international advanced level. It is widely used in the grinding and preparation of lithium-containing ores such as spodumene, lithium mica, and lithium feldspar, raw materials for battery-grade lithium carbonate, the grinding and powdering of roasting materials, and the grinding and preparation of various ternary positive electrode materials, such as cobalt salts, nickel salts, and manganese-based materials, as well as the preparation of coal powder for roasting fuel.If you need vertical mill to produce lithium powder, please contact us for equipment details.
