Acoustic cleaner is 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. It works by generating powerful sound waves which will vibrate the dry materials differently to each other and the surrounding structures. This will create a series of very rapid and powerful sound induced pressure fluctuations which are then transmitted into the solid particles of ash, dust, granules or powder. It causes them to move at differing speeds and debond from adjoining particles and the surface that they are adhering to.
