ABSTRACT:
Material dispenser apparatus includes a dispenser roll and dispenser roll cleaning brush mounted within the bottom discharge opening of a material receiving hopper for direct contact by the material in the hopper. The brush, being directly disposed to the material in the hopper, aids in displacing the material in the hopper toward the dispenser roll and compacting the dispenser roll with such material. Also, the brush clears the material from the dispenser roll as the brush and dispenser roll come into contact with each other. The speeds of rotation of the brush and dispenser roll are desirably each controlled independently of the other to permit them to be simultaneously rotated in the same direction but at different rpm for controlling the rate and size of material being dispensed. A material agitator may be provided in the material receiving hopper for working the material down within the hopper into contact with the surfaces of the dispenser roll and brush which are exposed to the material in the hopper. The material agitator includes a plurality of circumferentially spaced longitudinally extending agitator bars each of different lengths and supported at different radial distances from a rotating support shaft which may be driven by the same motor that drives the dispenser roll, but at a slower rpm.
