Process and apparatus for cooling extruder barrel. |
摘要 |
The method described here for cooling the barrel (10) of an extruder consists in causing a longitudinal flow of cooling air around the cylinder and over the length of each heating/cooling zone. Specially developed cooling plates (22; 25) make it possible to facilitate this longitudinal flow. An extruder cooled according to this method and equipped with such cooling plates wil have enhanced performance in so far as the temperature over a transverse section will be more uniform; furthermore, wear of the screw and of the barrel will be greatly reduced. <IMAGE> |
