Circular vibrating screens, also called circular-motion vibrating screens, are used to classify medium to coarse-grained bulk materials (5.0 mm to 100 mm) for screening.
Circular vibrating screens operate using indirect excitation of the screen mesh. The entire screen frame is driven by unbalance masses, which produce a circular vibrating motion.
Another key feature: The directionless vibrations of the circular vibrating system have a steep launch angle and the screen area must be further tilted in order to achieve a suitable transport speed. The optimum angle has been proven to be 15° to 30° in practice.
