Introduction Pneumatic conveying, one of the transportation methods of powdered and granular materials, uses air flowing in the pipe to transport the material.
The flowing air provides the energy needed directly to the conveyed material in the conveying pipe to carry the material from its original location to desired destination.
Although the pneumatic conveying systems are quite simple and eminently suitable for the transport of powdered and granular materials in factory, site and plant situations, because of the particle sizes, size distributions, and irregular particle shapes, conveying granular silica has been found difficult.
Fig. 1 Conveying system flow chart Fig. 2 Sketch of pipeline 2.2 Granular silica properties In the pneumatic conveying process, the nature of the granular material to flow and to resisting flow plays an important rule, such that we must well understand the physical properties of conveying materials and the gas-solid two-phase flow to properly design the pneumatic conveying.
