Key Takeaways. – Air classification is a process used to separate particles based on their size and density. – It is commonly used in industries such as mining, pharmaceuticals, and food processing. – Air classifiers can be used to improve the efficiency of various processes, such as particle size reduction and material separation.
Dynamic air classifiers. A dynamic air classifier uses the principles of elutriation, drag force, and centrifugal force to separate materials into coarse and fine fractions. A dynamic air classifier can classify a wide range of materials with particle sizes from 3 to 100 microns and can operate either inline or offline, depending on the process.
Fine powder separation equipment. Fine powder separation equipment operates by one of two mechanisms: mechanical separation or air classification. Mechanical separation uses screens that allow small particles to pass through while holding back and redirecting oversized particles. Air classification uses airflow to separate smaller, lighter ...
The optimization of these predictive response models resulted in the optimal values of air flow rate, feed rate, and guide vane angle for achieving better classification efficiency. This study establishes that the Box–Behnken factorial design combined with RSM effectively model the performance of circulating air classifier.

The surface moisture in stone sand limits the performance of air classifiers in aggregate plants or quarries. The drier the rock is (one to two per cent), the more dust can be removed, often allowing air classifiers to replace water wash systems altogether. ... However, in a pneumatic feed process, particles enter the air classifier at a much ...
Air classifiers separate materials by utilizing a dry process. Hydrocyclones, on the other hand, sort particles in a liquid suspension. Air classifiers can be used in aggregates production, manufacturing sand, industrial minerals production, as well as in mining operations. Hydrocyclones are most often utilized in mining applications.
In particular, the air classification process composed by a gravitationalinertial classifier followed by one or several centrifugal classifiers has been studied both numerically and experimentally ...

It has a compact design built with durable wear resistant materials, and delivers consistent, high-quality product regardless of variations in feed material. The Side Draft is capable of processing both ...
Air classifiers are normally employed when dry material particle size for separation is too fine for screening. The beauty of an air classification system is that it defeats the blinding and breaking issues associated with screening. The most significant advantage is its dry process for de-dusting aggregates.
