The powder mixing apparatus comprises a circular section cylindrical body having a longitudinal axis that is substantially horizontal, the body being leakproof and having two disk-shaped walls and an annular wall, the apparatus having a disk placed coaxially inside said body, the edge of said disk being substantially in contact with the annular wall so as to subdivide said body into two cylindrical compartments of substantially equal volume, said disk being provided on each of its faces with at least one blade for guiding said powder during rotation of said disk to a transfer orifice passing through said disk so as to enable at least a portion of the powder contained in one compartment to pass into the other compartment on each revolution of the disk, said blades being angularly offset, a horizontal drive shaft secured to the center of said disk serving to rotate said disk, and motor means serving to drive said drive shaft.
