Some transfer points experience this issue more than others depending on climate and material characteristics.  ![enhance material flow on conveyor transfer chute by applying air cannons](https://blog.martin-eng.com/hs-fs/hubfs/Picture%201.jpg?width=721&name=Picture%201.jpg) One solution, often overlooked, to combat this issue is applying a flow aid such as an **air cannon. **Air cannons provide **reliable, persistent, and forceful blasts of air** to safely and effectively clear material, returning it to the material flow.  ### Benefits of Air Cannons: \*Enhance flow when material conditions change, such as moisture or size \*Alternative to applying vibration for large structures or hard-to-reach areas prone to material bridging \*Nozzle and pipe options for various attachment methods/convenience \*Often small vessel sizes, such as 35-liter tank size, are effective \*Can be used in parallel with other transfer point techniques such as rock boxes  \* Martin® Roll Gen™ System easily pairs with air cannons to provide power in remote locations and increased safety measures. The Roll Gen™ provides both the signal and power to engage the cannon, firing only while the conveyor is in operation.

Are blockages perpetual or condition-based? 3. Is chute work structurally sound to support the air cannon and the blast from the cannon? 4. What controls are available for the air cannon, 110VAC/220VAC/24VDC, or an alternate source such as Roll Gen™. 5. The frequency and air pressure for firing to minimize air consumption and dust production while eliminating the blockage. 6. Ensuring the cannon only fires when the conveyor is in safe-operating mode.
