Paddle agitators are used where an uniform laminar flow of liquids is desired. Anchor Agitators : This simple agitator consists of a shaft and an anchor type propeller and can be mounted centrally or at an angle. . It is mainly used in reactors.Recommended For You: How to Select Motor Capacity of an Agitator? How to do Scale Up calculations? How to Design an Industrial Column? Paddle Agitators: This is one of the most primary types of agitators with blades that reach up to the tank walls. . They consist of two to four blades that move in a screw like motion. propelling the material to be agitated parallel to the shaft.Radial Propeller Agitators : Radial agitators consist of propellers that are similar to marine propellers. Send us a message Turbine Agitators : Yet another type of process agitator is the turbine agitator.Propeller Agitators : A propeller agitator is shaped with blades tapering towards the shaft to minimize centrifugal force and produce maximum axial flow. Turbine agitators can create a turbulent movement of the fluids due to the combination of centrifugal and rotational motion. . Propeller agitators are popular for simple mixing jobs. Helical agitators are most useful for mixing viscous liquids. just like the threads of a screw.Helical Agitators : These agitators have blades with a twisted mechanism. A simplified brief description has been tabulated below. The curves result in a vigorous motion of the fluids to be agitated.

These have tapering blades. These push and rotate the liquid in a laminar flow. For Flat Blade Turbine. Paddle. Anchor. . and it can be calculated as Number of agitators = (Maximum liquid height x specific gravity) / Diameter of tank. Gate. The diameter of impeller is 25% to 60% of tank diameter. Standard angle is 45 degrees. The width of blade is 1/8th or 1/10th of the agitator diameter. Cast agitators have two basic advantages. Axial Flow Turbine. Power requirement increases with higher pitch angle. There is no axial or radial mixing. These extend close to the tank wall and have tip speeds between 80 to 150 meters per minute. This produces maximum axial flow. These have tip speeds between 300 to 500 meters per minute.It is generally 4/5th of the diameter of the tank for Paddle. These have tip speeds between 200 to 300 meters per minute. Number of Agitators: There can be many number of agitators connected to a shaft. For Axial Flow Turbine and Turbo Propeller. uniformity of material and hard surface. Anchor. and angle of blade varies from root to tip. and disk diameter is 60% to 70% of the diameter of impeller. the angle of blade varies from 30 degrees (for less viscous liquids) to 60 degrees (for more viscous liquids). Type of Agitators and their functions: Marine Propeller is generally an item produced by casting process in a foundry and it has 3 or 4 blades. The diameter of Marine Propeller impeller is 15% to 30% of diameter of tank. Turbo Propeller and Flat Blade Turbine have blades ranging from 3 to 6. or Gate have only 2 blades. the length of blade is 25% of diameter. 1/3rd of tank Marine Propeller 100 . * 0.0 0.69 for 4 bladed. dia * 1.0 Agitator Shaft length = vessel length + (vessel dia x 0.300 RPM 5.300 RPM * 0. 1/3rd of tank Turbo Propeller 100 .6 for 3 bladed. * 0. * 1.6 for 6 bladed.6 for 6 bladed.45 for 5 bladed.33 for 3 bladed.0. * 0.25) For Rectangular Tanks.7 .35 for 3 bladed. * 0. 1/3rd of tank Disc Blade Turbine 100 .85 1/3rd of tank . dia * 1.5). * 0.6 for 3 bladed.0.34 for 4 bladed.300 RPM * 1. many factors for impeller can be decided.

UNKNOWN 1 JANUARY 2017 AT 17:37 which utility is suitable for condensing acetone vapours under vacuum and under atmposphere in condensor. 2.. and if you are able to maintain the vapour temperature above 15 deg C under vacuum. because the reaction mass temperature will be around 15-20 degC under vacuum.. there will be exchange of sensible heat also. give ur mail id so that i can share the sketch. remember to have a equalisation line from secondary condenser to collection receiver.pls. so mostly the vapours will reach equillibrium with utility outlet. AJAY KUMAR 2 JANUARY 2017 AT 21:13 using a better utility for condenser will enhance the rate of distillation. Reply Replies 1. ANSHU BHARGAVA 2 JANUARY 2017 AT 09:51 Can you explain theoretically and calculate and tell how to select utility as per the above post. if the temperature below 15 degC then use chilled brine at -20 degC. then go with -10 degC Brine or 5 degC chilled water. whereas in case of -10 degC brine. and in case of the vacuum distillation.chilled water 8 deg. the temperature difference can be considered as 7-8 deg C.. directly go with RT water at below 30 degC. for a chilled brine at -10 deg C. then go with chilled water for primary and chilled brine for secondary. and if you want to calculate it theoretically .1. if you are having two condensers. and for a utility like chilled water having a inlet temperature of 8 deg C.Anonymous. the temp difference will be around 3-4 degC..
