DENSE PHASE BY VACUUM
When pneumatic transport requires a high amount of material in the transport pipe, it is called pneumatic transport by dense phase. With which it is possible to mobilize large amounts of material in short periods of time, it is also usually used for the movement of material over large distances in considerable flows.
It is important to contemplate that not all materials can be transported in this way, it must comply with a series of characteristics so that the dense phase transportation is the right one. This type of
transport is adequate with high abrasive products or already elaborated mixtures; Due to its low speed the demixing possibilities are minimal.
A characteristic of this type of systems is that the air volume ratio compared to the product volume is 90 parts of product against 10 parts of air and a pressure differential greater than 4 atm.
