ABSTRACT OF THE DISCLOSURE A method and system for the detection of plate clashing in disc refiners are provided herein. The signal from either an acoustic or vibration monitor is processed through a filter which isolates those distinct predeter- mined frequencies at which a significant increase in signal level is known to occur during a clash or are generated in association with imminent or ac- tual plate clashing, the distinct frequencies being related to the clash and to the characteristics of the discs of the refiner. The signal level of the filtered data is compared with a threshold level at which protective action must be taken. Protection can be automatically initiated by the plate clash detection system, e.g., by automatically opening an electrical operation cir- cuit to at least one of a plate closing means, refining pressure retaining means and a motor turning the refiner plates. Alternatively, it can be done manually by an operator, using the detection system as a warning device.
