Lepidolite, also known as "limite mica", often contains rubidium, cesium, etc. Monoclinic. Often in the form of fine scaly aggregates. Lilac, sometimes yellow-green. Glass luster. It is mainly found in pegmatites, but also in griesites and high-temperature hydrothermal veins. It is a mineral raw material for lithium extraction. What grinding equipment is used for lepidolite grinding? Let's learn about the lepidolite ore processing process with Xiaobian.

Lepidolite is the most common lithium mineral and an important mineral for lithium extraction. It is a basic aluminosilicate of potassium and lithium, one of the mica minerals. Lepidolite is generally only produced in granite pegmatite, the color is purple and pink and can be light to colorless, with pearl luster, in the form of short cylinders, small flake aggregates or large plate crystals.
1. What are the applications of lepidolite?
Lepidolite is one of the main raw materials for extracting rare metal lithium. Lepidolite often contains rubidium and cesium, and it is also an important raw material for extracting these rare metals. Lithium is the lightest metal with a specific gravity of 0.534. It can produce lithium-6 required for thermonuclears, and is an important fuel for hydrogen bombs, rockets, nuclear submarines and new jet aircraft. Lithium can absorb neutrons and is used as a control rod in atomic reactors. It is used in military affairs as a red luminescent agent for flares, flares, and a thick lubricant for aircraft. Metallurgically used lithium to make light alloys and purifiers for metal products.
2. Lepidolite ore processing equipment
So what mill do you use to grind lepidolite? As an experienced pulverizer manufacturer, Guilin Hongcheng recommends vertical grinding mill for processing. Guilin Hongcheng has pioneered the research and development of the HLM vertical mill integrating drying, grinding, grading and conveying, aiming at the bottleneck of traditional pulverizers with low output, high energy consumption and high maintenance costs, based on the development trend of the industry, has set off a frenzy of imitation in the field of large-scale milling, and has become the mainstream equipment in the field of coal, cement, slag, non-metallic ores and other milling fields, and is also an important milling equipment for lepidolite.
3. Lepidolite ore processing flow
Lepidolite ore milling is generally divided into two types: lepidolite fine powder processing (200 mesh-400 mesh) and ultrafine powder processing of lepidolite powder (600 mesh-2500 mesh). The processing process is generally: mining and selection of lepidolite ore → crushing of lepidolite ore: generally crushed by jaw crusher to the fineness of the input material (15mm-50mm) that can enter the mill → lepidolite powder: fine powder Processing generally adopts HLM vertical mill and HLMX ultra-fine vertical mill for processing → storage and packaging of lepidolite powder: After the finished powder is collected by the mill, it is conveyed by air, screw and elevator, etc. It is transported to the finished product storage powder tank, and then uniformly loaded into the powder tanker or bagged. Proceed as follows:
Large pieces of lepidolite are transported to the raw material warehouse by special vehicles, and then the materials are sent to the jaw crusher by forklifts/manually for crushing, and crushed to a size smaller than the maximum feed size of the mill
The lepidolite crushed by the crusher is lifted by the elevator to the storage hopper, the storage hopper is discharged, and then the feeder feeds the host evenly.
In the grinding process, the qualified products are screened by the screening system and then enter the collector through the pipeline. After collection, they are discharged through the discharge valve to be the finished product. The unqualified products fall into the main engine for re-grinding.
The purified air flows into the blower through the residual air duct above the dust collector. The air path is circulating. Except for the positive pressure from the blower to the grinding chamber, the airflow in the rest of the pipeline flows under negative pressure, and the indoor sanitary conditions are better.
The above is the introduction of lepidolite ore processing process and application. The HLM vertical mill is used for lepidolite ore processing. The HLM super-large vertical mill is a large-scale milling production equipment carefully developed by Guilin Hongcheng. The equipment focuses on the field of milling, with strong adaptability to materials, advanced milling technology, high efficiency, energy saving and environmental protection, and a wide range of milling fields.
