The utility model relates to a coal gasification pressurization feed technical field, concretely relates to carbon containing solid material's mixed dispenser. This equipment presses mouth and discharge gate to constitute by material surge chamber, reducing fluidization room, gaseous phase nozzle, gas -solid mixing chamber, material accelerating chamber, weighing apparatus. Use the high pressure to carry gas as the medium, utilize the gaseous local negative pressure that forms in mixing the dispenser to suck the hybrid chamber with carbon containing solid material, realize the homogeneous mixing of gas, solid two -phase flow. Compare with the conventional art, this equipment uses coordinately with locking the system of fill, can widen solid material's application range, and bridging, jam, the reunion scheduling problem of avoiding the dense phase pipelining in -process to cause are changeed and is used in the through engineering approaches.
