Simatec circular vibratory screens are often installed as pre-separators or relief screens at the beginning of the engineering process. The circular motion coupled with the inclination gives the material the necessary impulse and ensures that the risk of plugging remains low.

However, Simatec circular vibratory screens are also used in classical screening for classifying medium to rough grained bulk materials up to a size of approx. 150 mm.

They are mainly used in dry screening and still occasionally in wet screening. The optimum screening angle, which is indispensable for the transport of the material, is between 10° and 20°.
