The Perfect Pair: Shock Pulse and Vibration Monitoring ...

2021-10-19  To further complicate things, grinding mills run at fairly low, and in some cases variable, revolutions per minute (RPMs). Under these conditions, traditional vibration measurement techniques alone do not yield clear answers. When combined with shock pulse measurement, on the other hand, these problems can be overcome in a solid technical solution.
