    Hello everyone<o:p></o:p>

    I would need your opinion on a problem I am facing.<o:p></o:p>

    I recently did vibration measurements on a jaw crusher.<o:p></o:p>

    From the spectral analysis, the vibrations seem to be caused by imbalance.<o:p></o:p>

    If someone has experience with such equipment, maybe you can help me with an idea about the possibility of balancing this equipment.<o:p></o:p>

    Can it be dynamically balanced like any other equipment or are there special balancing techniques?<o:p></o:p>

    Must there be a state of imbalance in the operation of this type of equipment?<o:p></o:p>

    I don't know if I should balance it or if this state of imbalance is normal.<o:p></o:p>

    Any opinion is welcome.<o:p></o:p>


    The crusher was under repair where the bearings were replaced and the foundation was rebuilt.<o:p></o:p>

    It probably had the same problem before, leading to the destruction of the foundation and bearings.<o:p></o:p>

    Now due to the imbalance (in my opinion), mechanical looseness appeared in the area where the frame is fixed to the foundation<o:p></o:p>
