Dense Phase Pneumatic Conveying – A Gentle Way to Convey

Dense Phase Pneumatic Conveying

Solutions for Bulk Materials Handling

Dense phase pneumatic conveying is ideal for transfer of abrasive, friable, or mixed-batch materials. Applications include key industry segments such as food processing, general chemical production, and manufacturing.

Selecting the proper pneumatic conveying system for powdered or granular bulk materials can be confusing as there are many variables to consider. But if product abrasiveness, segregation, or degradation is of concern, low velocity dense phase conveying is likely your best choice. Using a reduced rate of air to convey these materials means the process is gentler. This reduces wear on your equipment and breakage of the material itself. Lower velocity also minimizes separation of the materials being moved, saving you re-blending costs down the line. Learn more about the basics of dense phase pneumatic in the following videos.

What makes Nol-Tec’s approach to dense phase pneumatic conveying unique is our vast level of experience coupled with the use of Air Assists along the conveying line. By injecting air into the line at strategic locations, we decrease the required motive gas pressure and flow, resulting in reduced transfer velocity and increased system reliability. You'll also use less motive gas, saving you operation costs. This design allows us to incorporate our non-purge concept, where material is intentionally left in the conveying line, further minimizing ill effects from high velocity. Materials are less likely to plug or bridge when lines are filled, which helps prevent costly maintenance and downtime for your plant.

Providing straight answers for your company’s bulk materials handling is what Nol-Tec Systems is all about. You can rely on our expertise and value-oriented approach to deliver assured production efficiencies and long-term performance.
