How to Choose a System:

Correct selection of a Pneumatic Conveying System is governed by the following criteria:

Material properties / characteristics:

  • Particle shape
  • Mean particle size
  • Particle size distribution
  • Moisture content
  • Hygroscopic & Deliquescence
  • Friable
  • Adhesive-ness, Cohesive-ness, Explosive, Combustible
Capacity of conveying:
Process constraints:
  • Power Consumption
  • Wear Tear Due to Velocity
  • Segregation
  • Moisture Content
  • Hygroscopic & Deliquescence
  • Headroom & Space Constraint
  • Venting & Dusting Constraint
Capital cost Vs. Running cost comparatives

The choice of the right pneumatic conveying system is primarily governed by the material properties as well as the capacity and distance of conveying. For example, powders, pellets, and granules are preferably conveyed in a dense phase regime as it is optimal for these materials. Flakes are generally conveyed in the dilute phase due to their particle size and shape. Similarly, high capacities and longer distances are conveyed using dense phase systems, and conversely, low capacity, short-distance compact requirements are catered to by dilute phase systems.

Hence, the right choice of a pneumatic conveying system is best left to the experts, and rest assured, Macawber India guides you like none other!”
