Abstract: A system for moving large quantities of pulverulent material from receiving hoppers, such as those of a fly ash precipitator, into a pressurized air conveyor pipeline. Separate auger conveyors move material from a first line of receiving hoppers and from a second line of receiving hoppers into gravity material inlets at opposite ends of an effectively airtight casing of a pressure mechanical conveyor wherein auger conveyor screws of opposite hand move it toward a central outlet through which it drops into the pressurized air conveyor pipeline. The auger conveyors and the pressure conveyor augers operate continuously; and the system is cycled to alternately feed material into the pressure conveyor casing at receiving hopper pressure, which is about atmospheric pressure, and out of the pressure conveyor casing at pipeline pressure. The cycles of two or more pressure conveyors are out of phase with one another so they feed material into the pipeline consecutively to provide level pipeline flow.
