how to reduce the noise of sand machine work

Several Methods for Effectively Reducing the Vibration of ...

In the working process, the sand making machine will inevitably vibrate due to various reasons. If the vibration is long-term, it will cause the screws and other parts to loose or even fall off. This is one of the reasons we emphasize the need for regular maintenance of the sand making machine equipment.
