Title:
METHOD FOR OPERATING AN EXTRUSION SYSTEM AND EXTRUSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/137754
Kind Code:
A1
Abstract:
The invention relates to a method for operating an extrusion system (10) with the automatically executed steps of (a) detecting, on a time-dependent basis, at least two operating parameters (P), which are selected from the following list: (i) a screw rotational speed parameter (U), from which the number of rotations made by an endless screw (26) of an extruder (12) of the extrusion system (10) as of a predefined point in time can be determined, and/or (ii) a torque characteristic value, which describes the torque (M) applied to the endless screw (26), and/or (iii) an operating pressure in a cylinder of the extruder (12) and/or (iv) an abrasion parameter (C), which describes an abrasiveness of material processed in the extruder (12), (b) calculating, from the operating parameters (P), a wear parameter (V), more particularly a time for maintenance (Tw), which encodes a wear state of at least one component of the extruder (12), and (c) outputting a maintenance message, which encodes the wear parameter.
