METHOD FOR OPERATING AN EXTRUDER, AND EXTRUDER

The invention relates to a method for operating an extruder (10) that has a screw (14), comprising the steps: (a) detection of a formulation identifier (Ri) which is associated with material (20) to be extruded and which encodes at least one operating variable, from which an ideal screw rotational frequency (fi,soll) of the screw (14), which is to be set for the extrusion process, can be determined, (b) time-dependent detection of a throughput parameter (M), from which a throughput (m) of the extruder (12) can be deduced, (c) detection of a non-conformance (tp) point in time, at which the material (20) can no longer be produced with a predefined quality, owing to excessive wear of the extruder (12), and (d) calculation of a limit throughput parameter (Mi(tp)) from the throughput parameter(M), linking of the limit throughput parameter to the formulation identifier (Ri), and storing of the limit throughput parameter (Mi(tp)). 本发明涉及一种用于运行具有螺杆(14)的挤出机(10)的方法，具有如下步骤：(a)检测配方标识(Ri)，该配方标识属于待挤出的材料(20)，并且对至少一个运行参数编码，由该
