Dosage of highly disperse powders by ultrasound agitated tube modules

The handling of fine disperse powders also includes controlled powder transport and dosage as important operations. This study discusses the potentials of highly dispersed powder dosage in small quantities. The powder transport and dosage is realized by means of a new device using ultrasound agitation of closed tube modules. Visual observations of the emerging powder flow and optical measurement investigations show experimental results for transport continuity of different powder materials. The gravimetric dosage of bulk materials is determined by using a load cell measurement technique.
