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.
"What is the correct approach to each problem, arching, rat hole, etc?"
In case you want to check out the webinar, click below (please don't be too harsh with your reviews - I admitted my nerves got to me). 😬
"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.
Reduced downtime
Increased production
Better use of manpower
Reduced damage to equipment
Increased safety for workers
More of an art than a science 🎨
All about location (nozzle)
Flow aids are not cleaning devices
Air pressure affects the blast force
Tank size affects the blast duration
Make sure to determine the problem and the desired result
