In a Dense Phase Pneumatic Conveying System, dry bulk material is loaded into a vessel called the 'transporter'. The transporter is pressurized and the material is pushed out into conveying line in one continuous slug. Air Injectors are fitted along the line, which fluidize the material, or breaking it into easier-to-convey slug. This reduces the total system friction, and promotes flow at lower pressure.
The Dense Phase System moves the material at much lower velocity than a dilute-phase system, thus making it suitable for abrasive or degradable material also.
The material conveying at low velocity prevents material degradation & equipment wear. Dense Phase System also reduces segregation and promotes slow at lower air volume, making it more efficient per kg of material conveyed, compared to higher volume dilute phase conveying.
In addition, the system has the following features also:
