Ultrafine powders are typically defined as powders with a saiz Zarah of less than 10μm. With the advancement of science and technology, many industries require solid materials in powder form.
The powders needed must have small particle sizes, high purity, and no impurities. There are also specific requirements for the powder’s particle size distribution. As a result, ultrafine grinding technology and equipment are becoming increasingly widely used. Researchers are paying more attention to and focusing on ultrafine grinding technologies and equipment. Kilang jet udara technology is an important method for ultrafine powder preparation. It has become one of the preferred methods for developing various high-performance micro-powder materials.
Features of Kilang Jet Udara
The kilang jet udara, also known as an air mill or fluidized bed mill, uses high-speed airflow. This airflow causes collisions, impacts, and shear forces between the material and impact components. The product obtained through air jet mill has uniform particle size, narrow distribution, high purity, and smooth surfaces. The particles have a regular shape and good dispersibility.
During the grinding process, the material experiences minimal contamination, and it can even be done in a pollution-free and sterile environment. Therefore, it is suitable for ultrafine grinding in fields such as food and pharmaceuticals, where contamination is not allowed. Air jet mills do not release large amounts of heat during the grinding process, making them more suitable for grinding low-melting or heat-sensitive materials. The production process has a high degree of automation and is suitable for large-scale industrial production.
Application of Kilang Jet Udara
In military and aerospace fields, ultrafine powder materials are used to manufacture stealth materials for stealth aircraft and tanks. Rocket propellants made from air jet milled oxidizers and catalysts have a combustion rate more than twice that of conventional ones.
In the electronics field, ultrafine iron oxide powder can be used to produce high-performance magnetic materials. Ultrafine silica powder can be used to produce high-performance resistor materials. Ultrahigh purity alumina powder can be used to manufacture sapphire substrates for LED chips. Substrates made from ultrafine powder have good stability, transparency, and do not absorb visible light. After air jet mill, molybdenum powder has smaller particle size, narrower distribution, and improved bulk and tap density. This makes it more suitable for producing light bulbs, electron tubes, and integrated circuits.
In the new energy field, materials processed by air jet mill have fine average particle size, narrow distribution, smooth surfaces, regular shape, high purity, high reactivity, and good dispersibility. These properties meet the preparation requirements for electrode materials, leading to widespread application. Typical materials suitable for air jet mill include: litium manganese oxide, lithium cobalt oxide, litium besi fosfat, litium karbonat, spherical graphite, petroleum coke, asphalt coke, ternary materials, nickel-metal hydride alloys, ferrous oxalate, lithium titanate, and lithium nickel manganese oxide.
Kesimpulan
Air jet mill technology is an important method for processing micro- and nanometer-sized powders. Its research and development can significantly improve resource utilization efficiency. As the demand for fine and ultrafine powders continues to grow, pengilangan jet udara technology offers a sustainable and efficient solution for maximizing material yields while maintaining product quality.
