Abstract: A method for reducing impact damage to a waste fragmentation machine is provided in various embodiments. In general, material that is potentially ungrindable, e.g., unacceptably dense, may be inadvertently allowed to enter into the grinding chamber within the machine where it encounters a high-speed rotor. The high-speed rotor comprises rotor teeth that impact the material to fragment or comminute it to an acceptable size. A vibration detector is placed in proximity with the rotor's bearing(s) and, after taking a daily baseline sample, monitors the fragmentation process. If the vibration level goes beyond an alert upper limit, the operator may be alerted via visual and/or audible annunciation that potentially ungrindable material may be in the grinding or fragmenting chamber. The operator may then examine the waste material and, if necessary, remove any potentially ungrindable material.
