Planetary gear extruder with simplified sensor connections - has running rings at the ends of each planetary gear extruder module with identical connectors in the rings for attaching a temperature and/or pressure sensor and/or an injector

摘要

A planetary gear extruder has planetary spindles(10) whose ends are guided around running rings between the spindle modules. The temperature and/or pressure of melt in the extruder is measured at the running rings where similar connections(22,23) are used for both temperature and/or pressure measurement.
