The unique NAVCO® Bin Mapping methodology involves a detailed evaluation of the storage vessel and its intended bulk material. Recommendations are made based on a variety of factors including bulk density, particle size, moisture content, temperature, vessel size and shape as well as material of construction. NAVCO® pneumatic piston vibrators are sized for the application and their area of influence is determined. As shown in the Diagram below, the vibrators are located on the hopper so that the areas of influence overlap; vibrations are controlled through a sequence that provides optimal flow pattern and minimal utility consumption which is also provided in detail on a complete Bin Map Solution Drawing by NAVCO®.
