Pneumatic transport
Pneumatic transport is the movement of solids from one place to another by means of a compressible gas normally pressurized air. This movement is generated by the differential pressure, which will always be from higher pressure to lower pressure. Bringing the material from the place of greatest pressure to the place with the least pressure, by means of a transport pipeline that eliminates the pollution that comes from the plant’s environment, resulting in low maintenance because the equipment is safe from the continuously damaged by external agents. For transport, high, medium and low pressures can be used, in vacuum (negative pressure) or positive pressure (blowing).
General Concept
According to “Engineering of physical operations 1, Pneumatic Transportation. See Document
Classification and Types
Pneumatic transport systems have two classification mechanisms, by the concentration of the solid inside the transport pipe or by the pressure differential generation source.
