Abstract

A muffled concrete mixer device provided with a mixing tank (2) internally having mixing means (6) for the cement mixture, rotated on an rotation axis (R) by moving means (5) and rotatably supported by an arm (4), supported by a frame (3), for pivoting said tank (2) on an axis almost orthogonal to the rotation axis (R). The walls (13) of the mixing tank (2) include an external layer (11) and an internal layer (12), separated by at least an interspace (10) by means of which the sound emission generated by the cement mixture during the rotation inside the tank (2) is reduced.
