ABSTRACT:
This mixer comprises a cylindrical tank 5 having a fixed lateral wall 7 and a rotary bottom 9 rotatably mounted inside the lower part of the fixed lateral wall. It is characterized in that the rotary bottom 9 comprises a peripheral collar 18 overhanging its lateral face and forming an annular gap with wall 7, in that an annular projection 21 carried by this latter extends under the collar and defines therewith an annular chamber 22 extending between the lateral face of bottom 9 and wall 7, and in that the chamber communicates with the tank through the annular gap and emerges under the bottom 9 into a narrow annular slit provided between the lateral face of the bottom and the projection 21.
