The subject of this paper are screens with vibrating sieves. These machines differ from other industrial screens by the fact that only a sieve itself vibrates, while the riddle stays immobile. Special attention is given to a screen with a driving frame, which was built in Łódź Technical University. The authors give some results of process investigations of this machine. At present, the research is carried out on the sieve dynamics and amplitude distribution. The construction of the screen enables the implementation of rotating vibrators beside the electromagnetic vibrator, so the screen can be used in a wide range of research and industrial applications. The tested screen is built in an industrial scale and is designed for fine-grained materials.
