The statistical data is analyzed to detect whether one or more abnormal situations associated with an agitator of the stirred vessel exist.

The reactor vessel includes a first agitator for mixing in the reactor vessel.

A stirrer (50) disposed near the base of tank (46) maintains a well mixed solution within the tank.

A stirrer mill comprises a grinding vessel (2) and a stirring shaft (5) arranged such that it can be driven to rotate therein.

An agitator is provided for agitating fluid in the tank compartment.

The vessel also contains a magnetically operated stirrer (22).

A mechanized stirrer (224, 226) is also disclosed which enhances heating of contents of the kettle by stirring the contents of the kettle.

An agitator is mounted in the bowl for rotation therein.

In particular, polymerization is conducted in a reaction vessel equipped with a specially designed agitator that exposes the polymer melt partially filling the reaction vessel to inert gas flowing through the vessel.

An agitator is contained within each of the reaction vessels for stimulating liquid circulation within the vessels.

The bioreactor includes a reaction vessel, an agitator, a feed inlet, and an outlet.

A stirrer mill comprises a milling vessel (2) and a stirring shaft (5) arranged such that it can be driven to rotate therein.

An agitator (10) is disposed relative to the reaction vessel (2) such that the agitator (10) is capable of agitating the reaction mixture.

An agitated autoclave comprises an autoclave vessel, an agitator, and a mechanical seal.

A helical agitator (2) made of quartz glass is arranged in the tank (5), and one end of the helical agitator (2) is connected with the tank cover (14).
