    摘要: The invention relates to a method and an arrangement for cooling an extruded hollow product. According to the invention, the extruder (1) is provided with means for sucking air through the pipe (2). The air to be sucked is thus in contact with the inner surface of the pipe (2), cooling the pipe from the inside. Therefore the cooling of the pipe (2) can be realized in an efficient and simple manner. By arranging the sucking to occur from the middle of the conical extruder (1), no weld line will be formed in the extruded product, and the extruder (1) can be cooled effectively from the inside. According to the invention, the heat contained by the air that has been sucked through the pipe (2) can also be utilized.

    摘要: An extruder having at least one conical stator and at least one rotatable conical rotor. The rotor is mounted from its widest point with first and second bearings in such a way that the first bearing receives the forces acting in one axial direction of the rotor and the second bearing receives the forces acting in an opposite axial direction of the rotor. A method for using the extruder involves feeding a material to the extruder between the rotor and stator and rotating the rotor to cause the extruder to extrude the material.
