Variable elliptical vibrating screen: Particles kinematics and industrial application

Traditional vibrating screen usually adopts the linear centralized excitation mode, which causes the difficulty in particles loosening and low screening efficiency. The variable elliptical vibrating screen (VEVS) trajectory is regulated to adapt the material mass along the direction of the screen length, improving the particles distribution as well as the screening efficiency. In this work, a theoretical model was developed for analyzing the...
