  • Method for monitoring a grinding system and grinding system comprising a monitoring device
    Patent number: 8590391
    Abstract: The invention relates to a method for monitoring the load state of a grinding system having rotating grinding elements, the dynamic forces exerted by the grinding stock on the grinding elements being detected in a first frequency range which contains the fundamental oscillation of the grinding elements, and in a second frequency range in which the first harmonic of the fundamental oscillation occurs, and measures for reducing the load state being introduced when the first harmonic exceeds a predetermined threshold value in relation to the magnitude of the fundamental oscillation. Such a method permits very reliable and accurate monitoring of the load state of the grinding system.
