DESIGN AND ANALYSIS OF CYCLONE SEPARATOR
5.1 PRESSURE DROP The static pressure can be measured easily, whereas experimentally it is difficult to measure the dynamic pressure . at the exit. The pressure drop over a cyclone is normally . divided into three sections: • Losses in the entry, • Losses in the separation space (the main cyclone separator . body), and
Analysis of the effects of temperature and the share of solid and …
With increasing temperature, Re decreases, which significantly reduces the separation efficiency as well as pressure drop. Therefore, the present study analyses the impact of increasing temperature on the pressure drop and collection efficiency at an inlet velocity, U in = 12 m/s. Furthermore, we propose four novel cyclone designs that are a ...

The design of cyclonic pre-heaters in suspension cement kilns
Design of the cyclonic pre-heater cascade. From the previous findings, it has been recommended to operate all cyclones at a C s value below 3–4 kg/kg, thus considerably reducing the pressure drop of the cyclone cascade. This implies the use of a lower gas velocity in the bottom cyclones (an increased cyclone diameter).

How to Improve Cyclone Separation
Good cyclone separation depends upon control of pressure drop, pulp density and apex size. The 'pressure drop' may vary but should not change rapidly, and is held at safe levels by keeping an adequate sump level. A falling sump level causes cavitation in the pump and reduction in feed rate; pressure drop in the cyclone falls and …
