A PNEUMATIC CONVEYING (dilute phase) Solids mass flow rate: kg/h Mean particle size: micron Density of gas: kg/m^3 Density of solids: Vertical distance:
numerical simulation of dense-phase pneumatic conveying can complement experimental and theoretical studies which had promoted effect on the application and development of dense-phase gas solid flow in pipeline technique.
The key difference between pneumatic and hydraulic/slurry conveying of solids is that the carrier gas will expand continuously as it goes along the pipe. The flow regime in the pipe (dense or dilute phase) will depend on the ratio of gas to solids and the characteristics of the particles.
Dense phase pneumatic conveying has been investigated through simulation, using a dis- crete element approach for the granular particles and a ﬁnite diﬀerence method for the pres- sure ﬁeld.
Dilute Phase Pneumatic Conveying There are two primary methods of pneumatic conveyance: "dilute phase" and "dense phase." In dilute phase, relatively high volumes of air moving at high speeds are ... Bulk materials conveying calculations Trailer Coupling Blow Thru Adaptor.
A trial is organized to design an industrial dense phase pneumatic conveying line for a material that is sensitive to breakage. The industrial line must be able to convey 8 t/h, the pipe layout is 50 m including 15 m vertical and has 5 bends.
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 .
