ABSTRACT:
A device for cleaning a mixture of substantially granular grains containing differently sized particles comprises a housing (5) which has an inlet (11) for the mixture (1) on its upper side and an outlet (12) for the cleaned granules (18) on its lower side as well as a distributing plate (6). Cleaning gas flows through the granules falling down through the device against the direction of their fall. In the inlet area there is provided a guiding device (19) for the inflowing mixture (1) and a retention unit (2) for the larger particles (3). The distributing plate (6) is provided with a covering hood (16) having a recess (17) for the inflowing mixture. Between the distributing plate (6) and the covering hood (16) there is provided a slot (8), which preferably has a height of about 8 to 15 mm.
