A compacting apparatus is provided and includes a material supply line having an upright inlet portion and a transversely disposed lower outlet portion provided with a discharge opening at its discharge end. The lower outlet portion is supplied with high pressure air from an air supply line which includes an outlet end portion disposed coaxially within the lower outlet portion of the material supply line and is provided with a nozzle assembly for directing pressurized jets of air toward the discharge opening. The material supply line upper inlet and lower outlet portions, each, are provided with a circumferential air chamber operative to discharge air jets into the material supply line in a downstream direction about the outer periphery thereof and the air jets discharged from the circumferential air chamber provided on the lower outlet end portion of the material supply line coact with the aforementioned nozzle assembly air jets and are disposed immediately downstream from nozzle assembly air jets to facilitate the flow of material through the outlet end portion of the supply line and the discharge opening thereof, the discharge opening being reduced in inside diameter relative to the inside diameter portion of the material supply line in which the nozzle assembly and adjacent circumferential air chamber are disposed.
