When they first hear about our acoustic cleaning technology, many people think that audiosonics is the only solution we can offer to aid material flow ... and they would be wrong!

One of the biggest problems for sites with bulk storage silos is silo bridging where the stored material (cement, gypsum, carbon black, foodstuffs, etc) has built up on the inside of the silo walls.

The removal of this buildup has traditionally been done manually but putting humans inside a silo does not come without its dangers. So we developed 2 pieces of cleaning equipment to offer our clients, both of which used compressed air but neither of which use audiosonics:

  1. The Prima Whip™ for removal internal wall material buildup - see the special feature on previous blog post Prima Whip for cement silos in Egypt
  2. The Prima Lance™ for discharge blockage removal - see the special feature on our blog post Cement plant cleaning success


These pieces of equipment work independently, used in their own dedicated scenario BUT where a silo is completely blocked, they can be brought together to work in combination.

The Prima Lance™ is used to drill into the blocked silo from underneath which allows for the Prima Whip™ to then be installed on top of the silo remove the remaining material.

So if you ever have the unfortunate experience of a blocked silo, we have the answer. Contact us by email, Skype, telephone or fax and we will be happy to help.

We have both a technical brochure and CD rom with information about these exciting and incredibly useful non-acoustic technologies.



I am a truly innovative and affable Irishman who has over 35 years experience in a wide range of dry process and storage industries with particular disciplines in project engineering and consultancy.

Faced with a range of material flow and storage problems throughout my career my ambition was to find an affordable innovative and simple solution to prevent material blockages and build up and improve material flow within a wide range of dry process & storage industries.
