the origin. Solids loading ratio is the dimensionless ratio of the mass flow rate of the material conveyed to the mass flow rate of the air used. For powdered and granular materials values below about 15 generally relate to high velocity dilute phase conveying, and values above about 50 indicate that a material is capable of being conveyed at low velocity

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.
