Abstract (en)
[origin: WO8606770A1] The refiner process and the properties of the pulp produced are controlled by means of an accelerometer positioned on a refiner disc, which accelerometer measures high-frequency vibrations. The signal from the accelerometer is converted to vibration energy, which is utilized together with one or several other process variables for controlling and adjusting the process.
