Pneumatic Conveying Systems

The operating principle of the pneumatic conveying system is based on the transfer of kinetic energy from the compressed air flow to the granulated product being transported. In pneumatic transfer processes, every product carried by compressed air is first mixed with air and then separated from the air. The mixing process is done using rotary valves (air locks), loading stations, and Venturi systems, while the separation process is done using filters.

Pneumatic transfer systems that utilize vacuum pumps to leverage the power of vacuum created are referred to as vacuum pneumatic conveying systems, distinguishing them from traditional methods of transporting materials using compressed air.

The compressed air, which is a fundamental requirement for pneumatic conveying systems, is provided through channel blowers, Roots blowers, or high-capacity fans, depending on the air capacity and flow rate required by the system. Although pneumatic conveying systems may appear to simply mix the product with compressed air and then separate it using filters, they actually involve significant engineering work and expertise.

Dusts to be transported can acquire a high explosiveness characteristic under specific pressure and temperature conditions. Products that seem harmless, such as sugar, flour, and starch, can become extremely dangerous with improper design and selection.
