Agitation refers to the induced motion of a material is a specified way, for example circular motion in standard CSTR,

The entirely different operation from agitation is mixing.(the concept of phase homogeneity)

Mixing is the random distribution of two or more phases.

let's take a tank with cold water, it can be agitated but not mixed, to call it a mixing operation you have to add hot water which has different state of condition from cold water. Now the same tank has taken up from agitation operation to mixing operation.

Impeller : it's blades are designed in a way to carry liquid and provide centrifugal force to carrying liquid and increases velocity and volute is provided to convert high velocity into pressure.

Agitato: it is used to homogenise mixture in tanks, in simple words it mades provision of currents in liquid.
