Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
However a coal crusher generates large vibrations when crushing coal blocks which can affect the equipment itself as well as the safety of the structure [1 2] Although there have been few studies on the vibrations caused by coal crushers the research done on the vibrations caused by similar dynamic machines can be used to study them [ 3
