<p>The sieve device is used as a feeder and separator of materials which are difficult to separate such as household refuse, industrial waste, cumbersome or dry waste. In order to achieve an optimun distribution and cleaning effect, there are provided two superposed screen sieves (12, 13) comprised of overlapping bars having a conical cross-section and which are free at their ends. The cleaning effect of the device is improved by the step offset of the sieves (12, 13) and by the circulation effect resulting therefrom. The oscillation motion is obtained by means of oscillating elements made of rubber and by an uneccentric drive.</p> |
