The invention relates to a rotary cylinder which also serves as a heat exchanger. Said rotary cylinder has a jacket (1), an inner part (3) and an annular chamber (2) for channelling a cooling or heat transfer medium, said annular chamber being defined between said jacket and said inner part. The annular chamber (2) is sealed in the area of each cylinder end and the jacket (1) can be clamped in relation to the inner part (3) in the area of the cylinder ends by means of a clamping device. Said clamping device interacts with a sealing ring (10) and has a conical ring (15), a clamping ring (16) and at least one clamping screw (26). According to the invention, an annular rim (20) is provided at each of the cylinder ends as a reliable means of preventing the edge areas of the cylinder jacket (1) from expanding in a rotary cylinder of this type. Said annular rim (20) encompasses the jacket (1) in the area of the clamping device, and the inner part (3) in a recess (19) configured at each cylinder end, with essentially no clearance and with a positive fit. |
