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.
Pneumatic conveying can be used for particles ranging from fine powders to pellets and bulk densities of 16 to 3200 kg/m3 (1 to 200 lb/ft 3). Dil ute Phase versus Dense Phase Conveying. The specifying engineer typically has four choice in specifying a pneumatic conveying system. Dilute …
into "pull" systems that operate below atmospheric pressure, "push" systems that operate above atmospheric pressure, and hybrid "push-pull" systems, which are frequently used when materials need to be unloaded and then conveyed over long distances. Design considerations The design of dilute phase pneumatic transfer systems
From David Mills 'Pneumatic conveying system design guide' the solid loading ratio (ɸ) is 0.5. Therefore, ṁ = ρ × A × v = 8000 Kg/hr = 2.2 Kg/s Were ρ is the density of the mixture, A is the area of cross-section of the pipe and v is the velocity of discharge.
