Blocked silos and hoppers in carbon black plants can cause major plant shutdowns and loss of valuable bulk storage space and entry into silos for cleaning requires a large number of man hours due to Health and Safety considerations.

Acoustic cleaners automatically eliminate both material bridging and ratholing and ensure that the entire capacity of the silo can be utilised.

For these applications the acoustic cleaner is usually top mounted. In addition an acoustic cleaner can be mounted at the discharge end of a silo cone to prevent blockage and ensure maximum, continuous material flow.
