Cement Plant Pre-Heater Fan Acoustic Cleaning With Sonic Horns

Silo cleaning (preventing side wall material build-up and eliminating bridging) is something we have written about extensively before. A good example is a sonic horns blog post from last year entitled Giving New Meaning To Silo Cleaning as well as this key page on our main sonic horns website about Cement Bulk Storage Bin Cleaning & Silo Cleaning.

Silos, however, are not the only part of a cement plant where material build-up can be a problem and we find ourselves servicing an increasing number of enquiries for the cleaning of other plant elements such as pre-heater ID fans.

Particulate build-up on the blades can cause a pre-heater fan to go out of balance and if this happens during production, the whole upstream plant has to be closed down, the fan manually cleaned and then the whole plant gradually restarted. Such unscheduled downtime is very expensive. Typically, the build-up is an extremely hard, brick-like substance which can break off during operation and cause serious imbalance and possibly damage to the fan casing.

This video shows our 120Hz sonic horn in operation on a pre-heater ID fan at a cement plant in Malaysia. You can actually see the particles being debonded as the sonic horn sounds. Sonic technology at its effective best!
