Regularities of particle motion on vibrating conveyor

Abstract

Vibratory conveying equipment is widely used in industry and agriculture. The choice of operating parameters has a significant influence on the conveying velocity. Herein, the velocity of a particle under equal vibration intensity conditions is investigated using a frequency-adjustable vibratory feeder. The discrete element method was used to study the motion regularities of a particle on a vibrating conveyor. The effects of the amplitude, vibration direction angle, inclination angle, and vibration intensity on the transport velocity of the vibrating conveyor were investigated using the response surface method. The experimental and calculate results demonstrate that the simulation method and the model is reliable. When the vibration intensity is greater than Kc and remains constant, increasing the amplitude increases the velocity of particle motion. A large vibration direction angle enhances the throwing motion of the particle. A large inclination angle enhances the sliding motion. The inclination angle is used to increase transport velocity by enhancing forward sliding and attenuating backward sliding. The response surface analysis shows that the particle motion velocity is more evidently influenced by the amplitude, followed by the installation inclination and vibration direction angles. The results of the study are important for optimizing the design and operating parameters of vibratory conveying equipment.
