The rotary vibrating screen uses a vertical vibration motor as the excitation source. Eccentric weights are installed on the upper and lower ends of the vibration motor to convert the rotational motion of the vibration motor into horizontal, vertical, and tilted three-dimensional movements. Movement is transmitted to the screen surface. Adjusting the phase angles of the upper and lower ends can change the movement trajectory of the material on the screen surface.
