Flow-aids are devices used to promote the movement of bulk materials through hoppers, stockpiles, silos and chutes.
Bulk material flow through hoppers, stockpiles, silos or chutes can become compacted and is some cases blocked. Blockage types include rat holes, arches, bridges and clinging material.
An effective solution to build-up in hoppers, stockpiles, silos or chutes is the installation of an air-cannon system.
These Air Cannons or Air Blasters use compressed air to create an explosive force that is used to dislodge and prevent build-up, blockages and clinging material from the walls of hoppers, stockpiles, silos or chutes.
