Pneumatic Conveying System
When it comes to pneumatic conveying systems from your rail cars, silos or super sack unloading equipment, there are many considerations that determine how you should handle materials. For instance, the choice to use vacuum or pressure conveying can be as critical as it is entirely situational. Depending on the materials you and your operation are looking to convey, choosing between dilute phase and dense phase conveying will also better fit different processes. Ultimately an engineer will have to consider what is possible with the resources available and which methods will best suit the material being conveyed.
Safety, efficiency and cost represent just some of the factors to keep in mind when deciding between vacuum or pressure conveying. Whether or not material should be conveyed gently, ingredients should be protected against segregation (de-mixing) or if the effects of abrasion on your equipment should be minimized will determine whether dilute or dense phase conveying is appropriate in the end. Particle size of your material, its bulk density and other key characteristics also play critical roles when opting for either dilute or dense phase.
