A delivery and filling system for filling a cavity with a particulate material is disclosed. The system in one embodiment includes a hopper; a transport device, and a delivery chute. The hopper, transport device, and delivery chute each may have a porous distributor plate which partitions them into a first chamber and a second chamber. The system is hooked to a compressed gas source connected to the porous distributor plate and a fluidizer. A gas-control unit is provided including a pressure regulator, pressure sensor, and flow metering solenoid valve to independently regulate the flow of gas to the porous distributor plate and the fluidizer of the system independently.

1. A fluidizer apparatus for gravity feeding particulate material without causing the particulate material to cause dust or separate into sizes, said fluidizer comprising:a hollow tube having a first end and a second end; a porous distributor plate having a first side and a second side and attached to said second end of said hollow tube for receiving said particulate material on said first side thereof; a vent; and, a source of gas attached to said first end of said hollow tube, said gas having a pressure such that a gas bearing is formed between said first side of said porous distributor plate and said particulate material located thereon, so that said gas migrates through said particulate material and out of said vent but permits said particulate material to move off of said first side of said porous distributor plate.
