What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
phase conveying (Levy et al., 1997; Giddings et al., 2004) or fluidised bed applications (Benyahia et al., 2000; Ye et al., 2004). The main objective of this work was to investigate the prediction capability of a commercial CFD code when it is compared with the experimental observations of a dense phase pneumatic conveying system.
In a pneumatic conveying system, these materials cannot be ground down by the pneumatic conveyor or stuck between mechanical components, as they can in a mechanical conveyor. If you don't want your material scattered, spilled, ground up, or undesirably dispersed then suspending these particles in air through a pneumatic conveyor tube is an ...

A pneumatic system can convey a product at any place a pipe line can run. 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/ft3). As a general rule, pneumatic conveying will work for particles up to 2 inches in diameter @ typical density. By "typical
Sep 23, 2004· The phenomenon of electrostatic charge generation and its effects on granular flow behavior in a pneumatic conveying system was studied. The main parameters used for quantitative characterization of the phenomenon were the induced current, particle charge density, and equivalent current of the charged granular flow. These were measured using a digital electrometer, Faraday …

1.3 Design Tolerance The general principle of fluidized motion conveying is very simple and this method of conveying has a particular advantage of being essentially 'workable'. With pneumatic conveying systems it is critical that the conveying line inlet air velocity is correctly specified. Because air is compressible, and very much higher
but for vertical conveying it must be modified to D g u D f s s 2 0.057 = (9.15) The practical application of these equations is shown in Problem 1, which is a worked solution to be completed for a dilute phase pneumatic conveying system design. 9.3 Dense phase pneumatic conveying When the gas velocity is lower than that required to produce

The feeding of coarse particles (>0.5 mm diameter) directly into a riser operating at positive pressure is important for drying and pre-heating applications. The presence of the feeding device can lead to heterogeneity of drying and heating, and is the main factor responsible for pressure loss in short conveying systems. However, there is a lack of information concerning the axial and radial ...
