Johnson Matthey feasibility study success!
CPACT conducted a feasibility study on the data analysis of acoustic emission data collected by Johnson Matthey from the monitoring of an attritor mill. The work showed the benefits and capability of monitoring processes with low cost non-invasive acoustic emission sensors. It was possible to identify different operating conditions from the acoustic data using multivariate techniques such as PCA. Additionally the data could be correlated with simulations done by Johnson Matthey, giving further insight into the dynamics of the process. The study highlighted potential future work, and will inform any future investigations using acoustic emission at Johnson Matthey.
