Due to the physical and chemical properties of the product, the central material column drops instantaneously when the silo outlet valve is opened, while the surrounding material remains immobile.
For such inconvenient situations, a GUNJET Air Cannon by OLI is often the ideal solution. Other applications are the corners of rectangular-shaped bins or tiled silo outlet sections where hammering or vibration is unsuitable.
The GUNJET-type Air Cannon, which is activated electro-pneumatically, releases almost instantaneously a certain quantity of highly compressed air inside the silo or bin, thus provoking the typical effect of an explosion. GUNJET Air Cannons are particularly suitable for use with materials with a strong tendency to rat-holing. The GUNJET-type Air Cannon can be equipped with a control panel for adjustment of the air jet and the operation intervals.
