 It is, therefore, possible to directly reproduce laboratory optimization studies in a commercial production environment by switching from Converging to Barbell horns while maintaining high ultrasonic amplitudes.If correctly scaled up, the processes generate the same reproducible results on the plant floor as they do in the laboratory.Maximum achievable ultrasonic amplitude depends, primarily, on the properties of the material from which an ultrasonic horn is made as well as on the shape of its longitudinal cross-section.
