Pneumatic Conveying

  • Jacob Fruchtbaum


While pneumatic conveying uses more power per pound of material carried, it offers advantages under certain conditions. It occupies little floor space, makes possible moving material through crowded areas, is dust-free, except perhaps at loading and unloading points, and offers more safety. It requires less maintenance and less operating labor. It can run only from one definite point to another, except that, with switching devices, material can be diverted to any number of delivery points. There are two general types. The low-pressure type, commonly called Dilute Phase systems, uses the concept of air to carry a product in an airstream which is generally low pressure (under 15 psig), high velocity.
