ABSTRACT
The present study demonstrates the results of the research programme carried out at the Department
of Process Equipment, Technical University of Łódź, and concerns double-frequency screens. On the
basis of the research results the design assumptions of the industrial machine aimed at fine-grained
screening have been elaborated. It is widely known that the shape of trajectory in the oscillating motion
of the screen has a relevant meaning for obtaining of the best processing properties of the machine.
Therefore, the trajectories of oscillating motion, which will lead to the intensive segregation of the grain
layer moving on the sieve, have been searched for a long time. Seemingly, it is possible to obtain a double-frequency
screen. Two rotational vibrators of the same or different static moments are applied for the
drive of such a screen. As the name indicates, it is a screen which is characterised by two different rotational
speeds of those drive vibrators.
