Abstract
A pneumatic conveying system for conveying particulate material through a conduit that creates a strong laminar flow of materials and air surrounded by a boundary layer flow of air, such that long transport distances through dramatic elevation and directional changes can be achieved. Embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, an inner barrel and an accelerating chamber. Low pressure air is supplied to the system by the blower assembly and mixed with particulate material. The air/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other preferred embodiments, the particulate material is mixed with the air in the accelerating chamber.
