Sorting table with grading rolls comprising a number of grading or calibrating rolls (1) supported by end supports (3, 4), these grading rolls being positioned parallel in 5 succession to each other, so as to form a sorting plane, means enabling the rotational drive of said rolls (1) in the same direction, said rotational rolls being shaped or positioned so as to create at least one opening, or a number of openings (7) between two adjacent rolls, so as 10 to permit the pass-through and the drop-off of only the products to be sorted or calibrated, any foreign objects (CE) or products of a larger size than that of the products to be sorted remaining at the surface of the mobile sorting plane and being evacuated at its downstream 15 end (6), and means for modifying the gap between rolls, the end supports (3, 4) of the grading rolls (1) being mounted with a capability of limited translation on at least one lateral slide (11) orientated perpendicularly to the axis of said rolls, elastic elements (10) being 20 interposed between said end supports (3, 4) and means of actuation for bringing said end supports and the rolls supported by the latter closer together or moving them farther apart, in opposition to the antagonistic action exerted by said elastic elements (10), so as to decrease 25 or increase the cross section of the openings (7) for pass-through of the sorted or calibrated products, displacements in the opposite direction of said end supports (3, 4) and of the grading rolls (1) being achieved by the action of extension or compression of said 30 elastic elements (10), characterized in that said lateral slide (11) constitutes the means for rotational drive of the rolls (1, 2). 2974062_1 (GHMatters) P88663.AU 23/11/11 17a 17 15 2/12 16 16' 1 2 l a 2b . . .1 b 12-,+-- 6' 15 1. e 26 10 Figure 2 16, CE 17 O O2ap 27a 00O 30 11 29a0 0 30a C c Figure 3 |
