Mineral extraction of lithium can not be separated from a set of grinding equipment
Since 2021, new energy vehicles superimposed on the rise of the energy storage industry on the demand for lithium only increase, "lithium hot" led to lithium market supply and demand imbalance, lithium prices "high fever" (high running), the current production of lithium raw material battery-grade lithium carbonate prices have exceeded 600,000 yuan / ton. The price of battery-grade lithium carbonate, the raw material for lithium production, has exceeded 60 million yuan/ton.
Lithium resource distribution
Lithium element exists in the form of compounds in the earth's crust, mainly in the form of salt lake brine, hard rock lithium ore and lithium clay ore distribution, lithium minerals and lithium-containing minerals in nature has been found to be more than 150 kinds of minerals. Affected by the production cost and process maturity, lithium extraction from minerals is one of the most important ways to obtain lithium resources. Lithium extraction minerals are mainly lithium feldspar (containing Li2O5.8% ~ 8.1%), lithium mica (containing Li2O3.2% ~ 6.45%) and lithium aluminum phosphor (containing Li2O7.1% ~ 10.1%), other raw materials such as lithium feldspar (containing Li2O2.9% ~ 4.8%) and lithium iron mica (containing Li2O1.1% ~ 5%).
Lithium ore distribution
In China, lithium ore resources are not balanced around, Tibet and Qinghai Salt Lake lithium production cycle is long, high cost, technical difficulties; hard rock lithium ore is mainly distributed in Sichuan, Xinjiang, Hunan and other places. Among them, Sichuan hard rock lithium mines accounted for half of the country, ranking first in the country. In fact, there is a serious contradiction between supply and demand of lithium resources within China. The current reserves only account for about 6% of the world's reserves, while consumption accounts for about 60% of the world, the degree of external dependence reached 85%.
Lithium ore processing lithium
In order to "share a share" in the lithium market, enterprises around the world to seize the opportunity, have focused on lithium extraction from minerals. This requires a set of professional processes, including crushing and screening, grinding and grading, flotation and purification, tailings magnetic separation, etc., of which lithium ore crushing, screening and grinding at the front end of the process.
How to choose lithium ore grinding equipment
For mineral lithium extraction, lithium ore such as lithium pyroxene grinding system into fine powder, lithium ore grinding machine plays an important role in the middle. Lithium pyroxene processing fineness is generally 200 mesh, general mining machine MTW European mill and YGM high pressure suspension mill can meet the demand for lithium ore processing.
1.MTW European mill: the fifth generation of upgraded Raymond mill, absorbing the European grinding technology and concepts based on research and development, the model adopts a bevel gear overall drive, internal thin oil lubrication system, cage analyzer, arc air ducts, grinding rolls linkage pressurization and many other new milling technology, large output, environmental protection and safety, intelligent, easy maintenance.
2.YGM High Pressure Suspension Mill: the third generation of upgraded Raymond mill, with high pressure spring, overlapping multi-stage seal, new gear motor, environmental protection dust removal device and many other process upgrades, increased output, small footprint, fineness 20~400 mesh adjustable, the whole machine three bags of service.
Overall, the investment amount of the European version of the mill system is higher than the high-pressure mill system, you can inform the manufacturer of the output, inlet and outlet particle size size, the professional and technical personnel to give you a selection program and quotation budget for your reference.
