Superfine grinding of spodumene and lepidolite
What is Spodumene Lepidolite?
Lithium is a soft, silver-white metal that belongs to the alkali metal group of chemical elements. It is the lightest metal known to man and has the lowest density of any solid element. Lithium is highly reactive and flammable. So, it is usually stored in mineral oil. When exposed to air, lithium tarnishes quickly, forming a black oxide coating.
Lithium occurs in a number of different minerals, but the two main commercial sources are spodumene and lepidolite. Spodumene is a silicate mineral containing lithium and aluminium. Lepidolite is a mica-like mineral that contains lithium, aluminium and potassium.
Lithium carbonate (Li2CO3), lithium hydroxide (LiOH) and lithium chloride (LiCl) are the most common forms of lithium used commercially. Lithium carbonate is produced by treating spodumene or lepidolite with soda ash (sodium carbonate). Lithium hydroxide is produced by treating lithium carbonate with calcium hydroxide. And lithium chloride is produced by treating lithium carbonate with hydrochloric acid.
Lithium compounds have a wide range of uses, including: glass and ceramic production; primary aluminum production; grease production; welding rod coatings; pharmaceuticals; air conditioning systems; rechargeable batteries; high-performance greases; lubricating greases for extreme temperatures; heat-transfer fluids; and nuclear fusion reactors.
Ultra fine grinding mill
The ultra fine grinding mill is a new type of equipment developed on the basis of years of experience in the production of traditional powder grinders. It is mainly used for the processing of materials with Mohs hardness below 9 and humidity below 6%. The fineness of the finished product can be adjusted freely between 325 mesh and 2500 mesh, and the output can reach 20 tons per hour.
This ultra fine grinding mill has been widely used in the processing of materials such as talc, barite, marble, limestone, dolomite, fluorite, kaolin, bentonite and so on. It is an ideal choice for those who are looking for a high-performance and energy-efficient powder grinder.
What are the benefits of Ultra Fine Grinding Mills?
There are many benefits of using an Ultra Fine Grinding Mill when processing minerals such as spodumene or lepidolite. Some of the main benefits include:
- Increased recovery rates: Due to the increased surface area of the particles created by the ultra fine grinding process, more minerals can be recovered from the ore.
- Improved liberation: The finer particle size generated by the Ultra Fine Grinding Mill leads to improved liberation of the desired minerals from the host rock. This can result in an increase in overall recovery rates.
- Lower reagent consumption: The increased surface area of particles created by ultra fine grinding means that reagents can be used more efficiently, leading to lower overall consumption levels.
How do ultra fine grinding mills work?
The way that ultra fine grinding mills work is by using a combination of compression, shear, and abrasion to break down the minerals into smaller and smaller pieces. The most common type of ultra fine grinding mill is a ball mill, which uses steel balls to grind the minerals into a powder.
Another type of ultra fine grinding mill is a jet mill, which uses air pressure to break down the minerals into smaller pieces. Jet mills are typically used for more delicate materials that can be damaged by the high speed of a ball mill.
How to use ultra fine grinding mill?
In order to use the ultra fine grinding mill properly, it is important to follow the instructions that come with the machine. Here are some tips on how to use this type of mill:
1. Make sure that you have the right type of material to grind. This type of mill is designed for grinding very fine materials, so it is important to make sure that you have the appropriate type of material before starting.
2. Choose the right size of grindstone. The size of the grindstone will determine the amount of material that can be ground at one time. It is important to choose a size that is appropriate for the amount of material you need to grind.
3. Set up the machine properly. Before starting, make sure that all of the parts are in place and tightened down correctly. Be sure to read the instructions carefully so that you know how to operate the machine properly.
4. Start with a small amount of material. When using this type of mill, it is best to start with a small amount of material so that you can get a feel for how it works. Once you have a good understanding of how it works, you can increase the amount of material as needed.
