Pneumatic Conveying Systems eminently suitable for the transport of powdered and granular material in factory, site and plant situations. The systems requirements are a source of compressed gas, usually air, a feed device, a conveying pipeline and receiver to disengage the conveyed material and carrier gas.
The system is totally enclosed, and if it is required, the system can operate entirely without moving parts coming into contact with the conveyed material. High, low or negative pressure can be used to convey materials. For hygroscopic materials dry air can be used, and for potentially explosive materials an inert gas such as nitrogen can be employed.
Pneumatic conveying technologies are divided in vacuum conveying and Pressure Conveying.
