For the circular vibrating screen, the most common reason for the poor screening effect is the inadequate inclination of the screen surface, so it is necessary to pad the back support. In practical application, the inclination angle of screen surface is more suitable when it is 20 degrees. The inclination angle of circular vibrating screen is generally 16-20 degrees. If the inclination angle is lower than 16 degrees, … ## Dynamics and Vibrations: Notes: Forced Vibrations
