Air Cannons = More Of An Art Than A Science

I just completed two air cannon webinars this week (those always get the best of my nerves). However, once I get past the "stage fright," I enjoy presenting flow aid solutions to those struggling with material blockages. I also like conversing with the audience and answering their questions. Below, I will share 3 frequently asked questions in hopes they will enlighten you.

Frequently Asked Questions ❓

"What is the correct approach to each problem, arching, rat hole, etc?"

TypesMaterialObstruction If dealing with common blockages, as shown above, the environment and material characteristics will influence exactly how we approach the installation. There are many configurations and customizable aspects of applying air cannons to an operation. No matter the approach and configuration, air cannons are a viable solution to resolve clinging, arched, bridged, and rat-holed material. The flexibility of cannons allows you to have them fired by timers, downstream sensors, or manually when a problem is noticed.

"What disperses the flow in multiple directions inside the vessel?"

For example, a cannon operating one port and firing into a cone at 750 mph will create a force to bounce around within the cone. If you blast air into a void, no desired effect will occur. If air is blasted into the correct section of accumulated material, the blast will create debris and loosen the material. Once you know where and how to attack the material, the cannons will do their job properly.

"Why use air cannons over vibration on material transfer point chutes?"

Vibrators and air cannons are both effective flow aids. Depending on the material type, sometimes vibration is effective and air cannons aren't needed while other times, it is a dual effort and both are used throughout the operation. Certain materials are receptive to vibration while others require a mechanical introduction of force, like air cannons, to restore flow.
