A plate globally shaped like an upturned caisson with a bearing surface (10) for supporting and driving forward a bulk material layer to be cooled with a cooling gas passing through the platex. The plate front part (10b), viewed in the material forward motion direction, is formed with overlapping flanges (14) sloping upwards and defining transverse cavities (20) in the bearing surface and the overlapping parts of two adjacent flanges (14) defining narrow channels (22) for the cooling gas to pass through.
