What is another name for external vibration systems used in construction?

The term "shaker tables" refers specifically to external vibration systems used in construction, particularly in processes that involve the separation and sorting of materials based on weight or density. These tables utilize controlled vibrations to assist in the movement and distribution of materials, which is crucial in various construction applications like aggregate handling and concrete remediation.

This method of vibration provides efficient and effective ways to compact materials, ensuring a proper mix and distribution within forms or structures. Shaker tables can also be used to enhance the quality and strength of concrete by promoting uniformity and reducing the risk of air pockets, ultimately leading to a stronger final product.

In contrast, vibration dampeners are devices designed to minimize the effect of vibrations in machines or structures, but they do not serve the same purpose as external systems that actively apply vibrations for construction processes. Concrete mixers focus on combining ingredients to create concrete rather than applying vibration, while resonance plates are used in specific scientific and engineering applications rather than general construction practices.
