Implementation of predictive maintenance and dynamic analysis in paper industries

Increasing the 'operating speed' of existing Paper machines, has become an essential requirement in today's Industrial scenario. Maintenance of such machines especially after increasing the operating speed; has to be done with adequate preparation, monitoring, diagnostics and systematic implementation of maintenance corrections. This paper deals with the methodology of machinery problem identification including the critical assessment of the system natural frequency/frequencies, before and after increasing the operating speeds. The dynamic behaviour of machinery systems including the structures, dryer frames, etc. plays a very vital role on machines, before increasing the operating speed.
