An Overview of Ultrafine Air Classification
Ultrafine air classification is a particle size-based technique that is used as a means of separating particles with wide-ranging sizes, shapes, and densities through the use of a unique classification system. The classification system uses various size-determining mechanisms, such as sieves, screens, jets, and other physical or mechanical means, to classify and size particles down to the ultrafine range.
The main goal of ultrafine air classification is to separate material into differing grades through a sorting or selection process. This process is typically used in the industrial processing and production of materials, such as minerals, chemicals, and food products. The classification process is usually done on a commercial scale and requires specialized equipment in order to accurately measure, separate, and grade particles to the desired size.
In air classification, particles are typically classified according to their size and shape, and then divided up into two different categories. The first type of particles are referred to as air-fluidized particles, which are characterized by their sphericity and eccentricity. The second type of particles are referred to as commercially unable particles, which are characterized by their size, shape, and density.
The classification of ultrafine particles typically begins with the use of a sieve or screening device, which allows for size determination and separation. Depending on the type of material being processed and the desired end result, various additional devices or sorting methods may be utilized.
Air classification has many advantages over other types of sizing and sorting techniques. It is an extremely efficient technique with high accuracy and reliability, as well as being a safe and cost-effective means of separating particles to the ultrafine range. Additionally, air classification is able to handle finer particles than many other particle sorting techniques, and it can be tailored to a specific material composition or application.
Ultrafine air classification is a powerful tool for industrial applications and production and can be used to achieve particle size specs of high accuracy. It is used in a number of industries, including powder coating, paint and coating, food and beverage, plastics, and mineral and ore processing. Ultimately, the performance and results of ultrafine air classification is heavily dependent on the type of material being processed and the desired end result.
