Verfahren zum Temperieren eines Walzenteils eines Planetwalzenextruders

摘要

Tempering for a plastic working unit which has at least one mantle (1) and a worm, comprises a channel (2) for a tempering medium. The outside (3) of the mantle has a heating element (4) which provides additional tempering. The mantle is the roller section (5) of a planetary roller extruder or the cylinder of an extrusion worm in a two stage extruder. Tempering for a plastic working unit which has at least one mantle (1) and a worm, comprises a channel (2) for a tempering medium. The outside (3) of the mantle has a heating element (4) which provides additional tempering. The mantle is the roller section (5) of a planetary roller extruder or the cylinder of an extrusion worm in a two stage extruder. The tempering medium is water. Heat is supplied to the mantle from the heater, and additional heat can be supplied or removed by the tempering medium in the mantle channel. The temperature inside the mantle is managed by control of the heating element and/or the tempering medium.
