Jul 07, 2008· All the conditions at the intake of a pneumatic conveying system are known. Therefore the intake is chosen as the start of the calculation. In vacuum and pressure pneumatic conveying calculations, the used product properties are identical. The only difference is the mass flow, generated by a compressor in vacuum mode or pressure mode.
David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Solids loading ratios. The solids loading ratio, ϕ, is included on Figs. and and can be used in helping to identify the location of the operating point on these two figures, in addition to air and material flow rates. Any two of these three parameters can be used. For dilute phase conveying, maximum values that ...
