Abstract: An apparatus for the uniform, controlled distribution of free flowing material comprising a rotatable, vertically-oriented, hollow delivery tube mounted for rotation about a vertical axis within a fixed housing and driven by means of a motor external of said tube. At its upper end, the tube has an inlet port for receiving material and carrying it for distribution from its lower end by an integral system which includes apertures located in the tube walls, and a deflection member at the base of said tube for impelling the material out of the tube through the said apertures. The lower end of said tube protrudes from and is restrained by said housing.
