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.
Working principle:
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.
