Abstract
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.
