Air classification of solid particles: a review ScienceDirect
An interior space of a classifying device, where solid particles interact with air stream, is the separation zone. Four basic separation zones are known, as described by Rumpf [2], which include gravitational-counterflow, gravitational-crossflow, centrifugal Up to date, different types of air classifiers e.g., static and dynamic classifiers, have been developed. Static air classifiers adjust the target product size only Multi component modelling of an air classifier ScienceDirect

Comprehensive Knowledge-Driven AI System for Air Classification Process
Air classifier devices have a distinct advantage over other systems used to separate materials. They maximize the mill’s capacity and therefore constitute efficient methods of reducing the energy consumption of crushing and grinding operations. Since improvement in their performance is challenging, the development of an efficient Turbine air classifier is the main production equipment for ultrafine iron ore fines, which usually has an inferior classification accuracy and efficiency. To address the problem, in consideration of the relationship between the rotating speed of the impeller and the inlet wind speed, the inlet speed triangle is analyzed.涡轮式气流分级机压降分析及流场模拟

Establishment of a prediction model for the cut size of turbo air
The predicted values are strongly coincided with the experimental values for the testing samples of the different materials. This prediction model for cut size can be applied to different materials. (4) This study just analyzes geometrically structural parameters and uses a certain structure of a turbo air classifier.Observed from Fig. 6, when air rate is around 60 t/h, 53 t/h, and 44 t/h, the corresponding proportion of −90 μm particles is about 27%, 33% and 42%, respectively. The fineness of the classifier feed of survey 2 and 6 is the coarsest and finest due to with the highest and lowest air rate, compared with the others.Performance of the static air classifier in a Vertical Spindle Mill

Centrifugal air classifiers offer effective fines screening
Air classifier advantages. The accuracy of mechanical centrifugal air classifiers makes them ideal for when the separation curve or cut point is too fine for screens (200 to 400 mesh or finer), when the capacity is too large for screens (up to 800 tonnes per hour) and when system flexibility is required to meet various product specifications.
