Abstract (en)
[origin: WO2010028970A1] The invention relates to a method for monitoring the load state of a grinding system comprising rotating grinding elements, wherein the dynamic forces exerted by the ground material onto the grinding elements are detected in a first frequency range containing the base vibration of the grinding elements and in a second frequency range in which the first harmonic of the base vibration occurs, whereupon actions for reducing the load state are introduced if the first harmonic exceeds a pre-determined threshold relative to the magnitude of the base vibration. Such a method enables a very reliable and precise monitoring of the load state of the grinding system.
