Air classification has been employed successfully in several industries, such as the cement industry (Benzer, 2005) and the waste industry (Eswaraiah et al., 2008). A two-stage air classifier has been installed in an aggregate plant in Sweden to reduce the amount of fines.
The SD Classifier represents a highly versatile, energy-efficient system for the consistent separation of particles in the 100 to 400 mesh range. Compact design allows easy …
Air classification is a process employed to control or adjust the final product fineness of the grinding circuit where water interaction with the material is avoided. This technology was developed early in the 19th century to meet the demand of cement industry where tube mills with high capacities were employed.
Further the d 80 of the product showed that 500 g/t is the optimal dosage with 184 µm whilst the reference had 207 µm ( Table 1). The positive effect of grinding aids on improving product ...

classifier widely used in the cement industry has experienced three stages of centrifugal classifier, cyclone classifier and vortex classifier. The O-Sepa classifier, known as the third- generation classifier, was developed by Japan's Onoda Company in 1979. It retains the advantages of cyclone-type separator material dispersion, off-
An air classifier belongs to the most widely used classification devices in mills in the mineral industry, which is why there is a great interest in optimizing the process flow and pressure loss.
Used for controlling air pollution and in the food processing industry, air classifiers are also used for manufacturing cement, chemicals, cosmetics, pharmaceuticals, pigments, and other materials. When using an air classifier, the working principles behind its operation allow manufacturers to classify more efficiently and separate particles ...
