Feeding of pneumatic conveying systems

Abstract

Essential to the effective operation of a pneumatic conveying system is the efficient feeding of the solids into the pipeline. Feeding devices perform a variety of functions, including a sealing function, in which the conveying gas is essentially sealed from a storage hopper holding the product to be conveyed. Further, these devices might be required to accurately control the solids feed rate into the pipeline for process control features as in chemical plants or in dosing operations.
