The invention discloses a
pyrotechnic composition mixing mechanism.
Pyrotechnic composition enters a mixing drum from a high-end charging port and is discharged from a low-end discharging port, in the process, the rotating mixing drum drives the
pyrotechnic composition to rotate in an inner cavity of a drum body and pass through all screen meshes which divide the inner cavity of the drum body in the axial direction of the drum body, the
pyrotechnic composition is fully and evenly mixed due to ingenious combination of two movements, namely, inclined falling and rotating sieving, and requirements for both mixing efficiency and mixing quality are met.
