# Cyclone Separator Pressure Drop Calculation

cyclone separators selection guide | engineering360,because cyclone separators do not incorporate filter media or moving parts, the pressure drop (therefore, operating costs) and maintenance requirements tend to be low. they can also be constructed to withstand harsh operating conditions, and since separation in cyclones is a dry process, the equipment is less prone to moisture corrosion..design of cyclone and study of its performance …,present investigation the characteristics of flour mill cyclone are studied for various flow rates (inlet velocities) and its effect on performance parameters like pressure drop and efficiency are studied. cyclone is designed with two symmetrical tangential inlets and a single tangential outlet at the barrel top area where impeller is mounted..
