The air separators of third generation, born from the experience of Fema Engineering S.r.l. technicians, have their main application field in cement and minerals industries. The technical features for the air separators of the last generation comparing to the traditional separators, could be summarized as follows.

• Smaller overall dimensions.
• Extreme simplicity to control the fineness (can be obtained changing the speed of the classification cage).
• Minimal aintenance.
• Achievement of extreme fineness (also 100% < 45 µm).
• Higher efficiency in the classification, which is shown by the reduction of the thin parts remaining in the waste.
