ABSTRACT:
An apparatus for mixing powdered or coarse-grained bulk materials includes a first mixing device (4) with a second mixing device (11) lying below it, each of them having cylindrical mixing containers (2, 12) with downward tapering mass flow hoppers (3, 13). The bulk material from the upper mixing device (4) is conveyed via gravity pipes (9, 10, 10', 28, 29) into the second mixing device (11), which concentrically surrounds a third mixing device (6). Outlet apertures (27) are provided in the third mixing device (6) to ensure a constant discharge mass flow through the total lower outlet area (25).
