Conveying Characteristics of Pneumatic Conveyor : Part 4, Minimum Velocity of Air Flow through a Pipe Required for Conveying Granular Solid and its Pressure as to Blow Off the Plugging Layer of Solids in Pipe

Abstract

The authors have introduced a new formula for a minimum velocity of air flow required for the pneumatic conveyance of solid through a pipe. They have examined experimentally the minimum air quantity required for feeding a solid substance from a feeder of blow tank type. These studies are effective in deciding the air velocity and quantity required for the conveyance of solids through a pipe or to feed them from a feeder. Moreover they have introduced the formulas for the air pressure required for blowing off the plugging layer of solids in pipe.
