Patent ID: 7530731

Claim:
Mixing machine comprising: a container ( 10 ; 100 ) with a vertical axis of symmetry (X) inside which aggregates and binding fluids are introduced in order to form stone mixes; and at least one mixing unit ( 30 ; 130 A, 130 B) actuated by a motor ( 20 ; 120 ) so as to rotate about said axis (X) of symmetry of the container ( 10 ; 100 ); at least one blade ( 40 ; 140 A, 140 B) which forms part of said at least one mixing unit ( 30 ; 130 A, 130 B) and which acts on the mixes being processed and in turn rotates about an axis (Y; Y 1 , Y 2 ) parallel to and at a distance from said axis (X) of symmetry of the container ( 10 ; 100 ); characterized in that it also comprises at least one unit for dispensing said binding fluids inside the container ( 10 ; 100 ) which rotates about said axis (X) of symmetry of the container ( 10 ; 100 ) in synchronism with said at least one mixing unit ( 30 ; 130 A, 130 B), remaining constantly in a position angularly spaced from said at least one mixing unit.
