A new device has been developed to convey particles through a duct with air or gas. The pneumatic apparatus has an air box under a porous plate on which many inclined parallel plates are attached to orientate and convey particles from one cell to the next cell with air or gas. Thus, particles can be transported upwards as well as downwards. The average residence time or the apparent passing velocity of particles, the pressure drop of air or gas, and the power required to convey solids are investigated by applying the method of dimensional analysis. A minimum transport velocity of air is also evaluated, assuming a minimum voidage of particles mass within cells. As a result, they are expressed as functions of geometrical dimensions of the device, physical properties of particles, and of operational conditions such as the feed rate of particles, the inclination angle of the device and flow rate of air or gas. Experimental results verify the derived equations.
