Title: METHOD FOR MONITORING A SCREW CENTRIFUGE
Abstract:
The invention relates to a method for monitoring a screw centrifuge, in particular a solid-bowl or a screen-type screw centrifuge, comprising the following steps: • a) making available the screw centrifuge and processing a product with the screw centrifuge, wherein solids which are conveyed out of the drum (1) with the screw (2) are removed from the product, • b) determining a current angular speed and determining an average angular speed of the transmission input shaft (11) for the screw (2) over time, • c) evaluating the measurements from step b), and • d) outputting a warning signal and/or changing one or more operating parameters of the screw centrifuge if dynamic changes in the angular speed are detected during the evaluation in step c).
