Critical speed of agitator
WebThe performance of an industrial tank agitator can be directly affected by the critical speed of the shaft and impeller assembly. Operating an … WebJul 29, 2015 · When critical speed controls the diameter, this will require a gearbox capable of handling significantly more torque and bending than is actually required by the application. The result is a gearbox with a very high service factor that is more costly than required by the industrial mixer motor size and less efficiency because it is under loaded.
