Pressure Conveying
The conventional lean phase pneumatic conveying system employing a blower, metering valve, conveying pipeline, receiver and vent filter. Pressure conveying systems can operate at higher pressures than vacuum conveying systems, resulting in higher conveying rates for each pipe size. Air can be compressed using a positive displacement or"Roots" type blower for pressures up to about 1 BarG. There are no limits to the size of a pressure conveying system; very large blowers and pipelines can be used, but these may result in high power requirements.
