An air classifier is a sophisticated industrial device used for separating materials by size, shape, and density using air flow. This machine introduces materials into a chamber where a column of ascending air exerts an upward force, differentiating materials based on their aerodynamic properties.
Its operation capitalizes on the principle that various sizes and shapes of materials will encounter different levels of air resistance, thereby facilitating their separation. As a method of dry classification, it avoids the use of liquids, making it ideal for processing materials that are insoluble in water or oil, or that are challenging to separate in a wet state.
Employed in a variety of sectors, including food processing, chemical production, mining, and paper manufacturing, air classifiers are instrumental in sorting materials such as flour, plastics, and metallic ores. They are characterized for their ability to operate without liquids, adaptability to a broad range of material sizes, and capability for continuous operation. Available in gravity-based, inertia-based, and centrifugal models, air classifiers are selected to suit the specific separation requirements of the materials in question.
