Circular vibrating screen

A circular vibrating screen , often also called a circular vibrator, is used to classify medium to coarse-grained bulk materials (5.0 to 100 mm), for protective screening but also for drainage tasks. They represent a versatile solution for different sieving tasks.

Circular vibrators are screening machines with indirect excitation of the screen mesh. The entire sieve frame is moved by unbalanced masses that generate a circular oscillation. This means that only slight acceleration of the material to be screened is possible. For this reason, circular vibrating screens are primarily suitable for separations in the medium to coarse grain range. The non-directional oscillations of the circular oscillation system have a steep throwing angle, so that the screen surface must also be inclined so that a sufficient transport speed is achieved. Investigations show that the optimal inclination of a circular oscillator is reached at an angle of 15 ° to 30 °.
