An agitator is composed of a drive device ( motor, gear reducer, belts…), a guiding system of the shaft (lantern fitted with bearings), a shaft and impellers . If the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is ...

Agitator / Mixer for Vessels

As we shall see, the required power is very different as a function of impeller diameter. Impeller power draw is equal to the impeller power number, N P, times the density of the fluid, times the shaft speed cubed and the impeller diameter to the 5 th power: 3) P = N P ρN 3 D 5. Power number is also dependent on Reynolds number and D/T ratio.

The vessel was equipped with a single large baffle of a width of 0.2T immersed to a wetted depth of 0.3T which was found to be the optimum arrangement in their study. Covering a rather narrow range of impeller off-bottom clearance-to-tank diameter ratio (C/T) between 0.11 and 0.33, they ...

Information for Agitator / Mixer

Vessel diameter; The size of vessel used for mixing will determine the diameter of the impeller. A general rule of thumb for axial or radial flow patterns is the diameter of the impeller be ⅓ of the vessel's diameter, so a 10 cm beaker would require approximately 3 cm impeller.
