These separators have a better separation efficiency due to the external fan and the cyclones. - Comparison between cyclones and conventional separators: The diagram here below shows the specific surface (Blaine) produced in order to achieve a certain percentage of residue on 30µm (From Duda Cement Data Book). -
In cement manufacturing industries, large-sized cyclone separators are used as main process equipments in significant numbers for handling high volumetric flow rates of dust-laden gases. - The cyclone is a simple mechanical device commonly used in the grinding circuits to remove relatively large particles from gas streams.
Dynamic separators are classified in three categories (*), the first, second and third generation.: In first generation separators, the air flow is generated by a fan within the body of the classifier. - In second generation, the air flow is generated by an external fan and there are cyclones.

Cement Seperator. Application: In cement industry production, in order to improve the efficiency of the grinding system and reduce the energy consumption of the product, a circulating grinding system is now widely used. As an important part of the system, the advanced performance of the classifier directly affects the efficiency of the system.
ball mill air separator efficiency formula For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30%
These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.
