ABSTRACT OF THE DISCLOSURE An elongated, horizontal and at least partially closed air jet dispersion and air jet entrained material deceleration zone is provided and one end of the zone includes at least skewed velocity distribution nozzle of the circular Coanda surface-type opening inwardly along the zone toward the other end thereof. The zone includes discharge structure defining a plurality of downwardly opening gravity-type outlets spaced longitudinally along the zone and duct structure for flowing air and airflow entrained solids there- through at high velocity is provided. The duct structure includes an outlet end opening into the nozzle and an inlet end open to the ambient atmosphere and positioned to receive gravity discharged solid materials from the outlet spaced one outlet from the aforementioned one end of the zone. A first form of the invention utilizes a central high velocity air jet directed into the inlet end of the duct for causing airflow through the duct and a second form of the invention utilizes a high velocity annular jet of air introduced into the duct intermediate its opposite ends with that annular jet axially centered relative to the corresponding portion of the duct and flush with the inner surfaces of the duct. Further, structure is provided whereby the radial ex- tent of the annular jet may be adjusted.
