Resonance conveyors, also known as vibrating conveyors are dual-mass vibrating systems that are used to convey bulk materials over relatively long distances. The main distinct feature from other types of conveyors such as belt and screw conveyors is that it consists of dynamic thrust springs which create directed vibrations. The vibrations are produced at the base frame and increased considerably as they approach the conveyor trough. There are various types of resonance conveyors, and it is essential to understand them so as to purchase the ideal one for your applications.

Resonance conveyors can be broadly categorized in three ways based on their design and configurations. These are anchored, balanced, and isolated frame conveyors.

Anchored conveyors

These types of resonance conveyors are configured in such a way that the base frame is anchored directly to the foundation for support. The dynamic restoring forces of the spring are also supported by the foundation; hence, the machine requires very little drive power. This is the key feature of these conveyors and it should be considered when designing the floor. A reinforced concrete floor that's properly sized is the most suitable for supporting anchored resonance conveyors.

This type of conveyor belt is most suitable if you are considering it during the construction of infrastructure as it is easy to incorporate the structural requirements for the placement of anchored conveyors. This will save you from making costly structural changes to the foundation in the future.

Balanced conveyors

In these types of resonance conveyors, the conveyor trough and the base frame have the same weight capacity. Both of these components move in the same frequency but in different directions. The weight balance between the conveyor trough and the base neutralizes vibrations and prevents them from being transmitted to the floor. The system is mounted on vibration-damping springs which also minimize the vibrations transmitted to the base.

Balanced resonance conveyors are suitable for applications where there is need to minimize environmental vibrations during operation.

Isolated frame conveyors

Isolated frame conveyors consist of a heavy base frame with elastic components. The elastic components act as the anchor on which the base stands and help in minimizing the vibrations and forces transmitted to the ground during operation. The weight of the base also helps in absorbing vibrations. 

Like the balanced conveyors, isolated frame conveyors are also suitable in applications where there should be no transmission of vibrations to the environment.

Resonance or vibrating conveyors are ideal equipment for industries that deal with material handling. They are easy to operate and have low maintenance costs, making them efficient and cost-effective. With an understanding of the various types of resonance conveyors, you can be able to choose the most ideal one for your industrial applications.
