Pneumatic Conveying, Performance and Calculations! Bulk-Blog
Jul 07, 2008 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. The calculation result should be the capacity at a certain pressure drop. However, both these values are not known.

Pneumatic Conveying For Bulk Dry Materials - STT Systems
Dense phase pneumatic conveying is an intermittent or batch process where pulses of high pressure, low velocity air propels a slug of material to another location. This differs from dilute phase as the material-air ratio is much higher and, as a result, dense phase conveying is often used for materials that are friable or susceptible to product ...
