Abstract (en)
[origin: EP1317969A1] The treatment plant has a hopper (5) to receive the raw mineral materials, such as earth, rubble from road surfacing or recycled concrete, at least one riddle (10) fed by an extractor (8), and at least one conveyor (12). The riddle (10) has a first section (10a) for separating a first fraction of the mineral material, situated above the first conveyor, and a second section (10b) for separating a second fraction of the material, located above a second conveyor (16) that has one end overlapping the end of the first conveyor (12). The riddle has star wheels or discs on shafts that are rotated at different speeds in its two sections.
