Abstract:
Ultrasound technology has become an important aspect
in material handling and machining. This paper describes the
application of standing and traveling ultrasonic waves in powder
transportation and how their usefulness in feeding, dosing and
supply of small amounts of powder with high accuracy. Piezoelectric
actuators have been used to generate the ultrasonic waves in various
devices. These devices have presented a unique and simple means
of accurate transportation of powder.
