Lithium mica used to be rare but became relatively easy to obtain until nearly a decade ago. It is sometimes a large round-bundled aggregate, or it may be a small flattened continuous mass, but it is most commonly a pinkish-purple microcrystalline burrstone with a shiny surface when exposed to light. Lignite is a subspecies of mica, colored by lithium and used industrially as an insulating material.325 mesh lithium mica powder belongs to the application of ultrafine powder, and the LUM Ultra-fine Vertical Mill is the ideal machinery and equipment for powder making.
LUM series ultrafine vertical mill is a new type of ultrafine grinding equipment designed and developed by Liming Heavy Industry based on 30 years' experience in research and development and manufacturing of four generations of mills, and based on LM vertical mill and introduction of modern ultrafine vertical mill's roller technology, which can be widely used in ultrafine grinding of nonmetallic minerals, such as calcite, marble, limestone, bicarbonate, talc, barite, dolomite and so on, and it is the ideal equipment for large-scale construction of large-scale plant of powdering of nonmetallic minerals. Ideal equipment.
I. What are the performance advantages of LUM Ultrafine Vertical Mill?
1, to realize the principle of ultra-fine grinding and specially designed roller sleeve and liner grinding curve, used for ultra-fine powder grinding, easier than ordinary vertical mill to form a material layer, so that the mill once grinding to the required fineness.
2、Adopting the principle of multi-head powder selector, and each rotor can be frequency control, the fineness of the finished products can be realized within the selected range, without the need to go through the second wind selection and grading, and there is no presence of inferior materials.
3, pre-compaction device can ensure that the grinding part of the more effective "eat material", so as to achieve a very fine grinding; ultra-fine vertical mill vibration is small, the power has been effectively played.
4, the grinding roller lubrication adopts a separate lubrication station, and a single grinding roller circuit adopts double pumps, suction working mode, not only to make the grinding roller bearings to get sufficient lubrication and cooling, but also to ensure that the grinding roller bearings indoor will not be too much storage of oil, which will lead to leakage.
5, PLC / DCS automatic control of the grinding roller pressurization control mode, grinding pressure is accurately controlled, and does not require manual operation. Meanwhile, it is equipped with mechanical limiting device and electronic limiting device to prevent direct contact between roller sleeve and grinding disk liner, which avoids destructive impact and violent vibration.
II, the use of lithium mica after grinding?
1. Lignite is one of the main raw materials for extracting rare metal lithium. Lithium mica often contains rubidium and cesium, which are also important raw materials for extracting these rare metals. Lithium is the lightest metal, with a specific gravity of 0.534. It produces lithium-6 for thermonuclear applications, and is an important fuel for hydrogen bombs, rockets, nuclear submarines, and new jet aircraft.
2. Lithium absorbs neutrons and is used as a control rod in atomic reactors, in the military as a red luminescent agent in flares and flares, and in airplanes as a viscous lubricant. In metallurgy, lithium is used as a purifying agent for light alloys and metal products.
