Abstract
A bulk material mixer includes a container accommodating a central tube provided with a plurality of lateral inlet openings at various levels. The inlet openings have a cross section which increases from bottom to top so that the inlet openings at the lowest level have a smallest cross section while the inlet openings at the uppermost level have a greatest cross section.

A mixing device in particular for bulk material, comprising:
- a container defining an axis;
- and
