Ultrasonic augers for improved transport of granular materials
Ultrasonic augers for improved transport of granular materials
This paper explores the superposition of ultrasonic vibration on vertical rotating augers in a variety of granular media. Ultrasonic vibration is known to facilitate direct penetration of granular media, and it is anticipated that any related reduction in the torque requirements of a rotating system might improve augering performance. Experimental results suggest that, compared to the non-ultrasonic scenario, ultrasonically assisted augering significantly promotes the flow of granular media, while moderately reducing the torque required to operate the device. Furthermore, it was discovered that particle size, helix angle, and auger speed all affect the performance of the auger in different ways as the ultrasonic amplitude is adjusted.

Abstract
This paper explores the superposition of ultrasonic vibration on vertical rotating augers in a variety of granular media. Ultrasonic vibration is known to facilitate direct penetration of granular media, and it is anticipated that any related reduction in the torque requirements of a rotating system might improve augering performance. Experimental results suggest that, compared to the non-ultrasonic scenario, ultrasonically assisted augering significantly promotes the flow of granular media, while moderately reducing the torque required to operate the device. Furthermore, it was discovered that particle size, helix angle, and auger speed all affect the performance of the auger in different ways as the ultrasonic amplitude is adjusted.
