Abstract
A dilute phase pneumatic materials conveyance apparatus is disclosed having a pneumatic accelerator which is capable of conveying materials through a gas stream which is selectively patterned. The conveyance apparatus also includes a source-gas manifold and control apparatus which enable selective control of the apparatus on a real time basis to achieve desired gas pattern flows through the apparatus to achieve selected particle dispersion, isolation, stratification, electrification, classification and entrainment of material and to convey it through a processing conduit. The configuration of the conveyance apparatus also enables further processing, including drying, sorting, pulverization and classification of the materials. The conveyance apparatus also enables classification of materials based on the aerodynamic diameter of the particles being conveyed because of the ability to achieve particle isolation.
