THE KINETIC EXTRUDER: A DRY PULVERIZED SOLID MATERIAL PUMP

摘要

Method and apparatus are shown for the continuous feeding of pulverized material to a high pressure container (2). A rotor (12) is located within the high pressure container (2). The pulverized material is fed from a feed hopper through a stationary feed pipe (4) to a vented spin-up chamber (10) to a plurality of two-stage sprues (32) mounted in the rotor (12). Control orifices (38) downstream from the sprues meter the flow of coal through the sprues (32).
