Jun 16, 2014· Another consideration for dense phase conveying is the overall conveying distance. This limitation is essentially imposed by gas compressibility and the practical limit in terms of pressure drop in pneumatic conveying systems. The longer the conveying system is the lower the mass flow rate of material that can be achieved for a given pressure drop.
