One of our distributors in Europe recently contacted me about an application to move plastic chips and pellets (shown above). In this application the customer needed to move the material 6m vertically (upward), 10m horizontally, and then 4m vertically (downward) at the fastest rate possible using an EXAIR Line Vac. So, we needed to determine the most suitable model number.
When determining the proper model Line Vac for pneumatic conveying applications, we investigate specifics such as:
Bulk density of the material
Shape/size of the material
Required conveyance rate
Available compressed air supply
Using this information we can make a recommendation as to the best Line Vac for the application. For this application, the bulk density of the material was between 10-15 pounds per cubic foot, the size was relatively small, our distances were given, and the required conveyance rate was “as much as possible”. With a sufficient compressed air volume and pressure of 80 PSIG, we knew everything we needed to make a model number recommendation.
Due to the significant height as well as the considerable horizontal distance, the best solution for this application was a Heavy Duty Line Vac. Given the small size of the material, several options “could” move the chips/pellets, but we needed to determine which Line Vac would move the most volume. Our recommendation was to use the Heavy Duty 2” Line Vac, model 150200, which we estimate could move ~400 pounds per hour (or more) in this application.
Conveying materials pneumatically removes worker interaction with the movement of the product, allows for controlled ON/OFF cycling of material transfer, and eliminates fatigue related to physical handling of the material.
If these aspects could benefit your facility or application, contact an EXAIR Application Engineer.
