Acoustic cleaning

The new bells made from 316 spun steel have no problem with rust and are ideal for sterile environments such as found in the food industry or in pharmaceutical plants.

From 1990 onwards the technology became commercially viable and began to be used in dry processing, storage, transport, power generation and manufacturing industries.

An acoustic cleaner 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.

A typical selection of frequencies available would be as follows: The introduction of acoustic cleaners has been a significant improvement in many areas of health and safety.

Air cannons, soot blowers, external vibrators, hammering or costly man entry are all superseded by noninvasive sonic horns.

Previously the problem was addressed by manual cleaning from underneath the silo which in its turn introduced significant risk from falling material when the blockage was cleared.

Older material compacted on the side of a silo can also start to degrade and produce dangerous gases.

An acoustic cleaner will produce sound waves which will make the compacted material resonate at a different rate to the surrounding environment resulting in debonding and clearance.
