Pneumatic transport

Principle of operation and use

Pneumatic transport in the “dilute phase” makes it possible to handle powdery and granular products at a more or less long distance and using compressed air at low pressure (<1 bar).

The transport of the product is carried out continuously. The product is introduced into the pipe (circuit) by a rotating sluice via an injector element or directly (through sluice). The superpressed air is produced by a booster or a blower.

A distinction is made between two principles of pneumatic transport in the dilute phase: 

- The positive pressure system (blowing)
- The negative pressure system (suction)

The choice between these two principles depends on the physical characteristics of the products and on the desired flow rates.
