'''Acoustic Cleaners''' are used wherever there is a build-up of dry materials and particulates which need to be cleaned regularly to ensure maximum efficiency, and minimize maintenance and down time. An acoustic cleaner works by generating powerful sound waves which will vibrate the dry materials differently to each other and the surrounding structures. | '''Acoustic Cleaners''' are used wherever there is a build-up of dry materials and particulates which need to be cleaned regularly to ensure maximum efficiency, and minimize maintenance and down time.

*Importantly they prevent the material build up problem from occurring in the first place. These advantages mean that the financial payback is often very quick. It is also possible to compare acoustic cleaners directly to alternative solutions. | *Importantly they prevent the material build up problem from occurring in the first place.

*Air cannons. These are well established but are expensive with limited coverage thus requiring multi unit purchase. They are also noise intrusive and have a high compressed air consumption. | *Air cannons. These are well established but are expensive with limited coverage thus requiring multi unit purchase.

*Vibrators. These are easy to fit to an empty silo but can cause structural damage as well as contributing to powder compaction. *Low friction linings. These are very quiet but are expensive to install. Also they are prone to erosion and can then contaminate the environment or product. | *Vibrators.

*Inflatable pads and liners. Again these are easy to install in an empty silo. They help side wall build up but have no impact on bridging. They are also hard to maintain and can cause compaction. | *Inflatable pads and liners. Again these are easy to install in an empty silo. They help side wall build up but have no impact on bridging.

*Fluidisation through a 1 way membrane. This can help already compacted material. However they are expensive and difficult to install and maintain. They can also contribute to mechanical interlocking and bridging. | *Fluidisation through a 1 way membrane. This can help already compacted material.
