For the air conveying of light bulk materials, the most common and applied method is the pneumatic conveying in diluted phase.

This system is also known as “flight transport” or “low pressure” and is characterized by the low efficiency ratio between the quantity of product used per kilogram of air.

The transport speeds are usually 20 – 30 meters per second and finds its greatest applications in the following sectors:

  • PVC production
  • Transformation of plastic materials
  • ceramic
  • cementizio
  • food
  • Pharmaceutical
  • Cosmetic
  • milling

In general, pneumatic conveying is used for the handling of light bulk materials in the form of powders or granules.

Pneumatic conveying can be done in  2 ways, namely:

  1. “In push”, using positive pressure
  2. “In suction”, using negative pressure
