Abstract: Waste grinding apparatus comprising a grinding cell in which at least one rotor is housed, the rotor being driven by an electric motor located outside the cell and controlled by an electronic unit, wherein the rotor comprises a central body (13) defining at least one radial vane (15a,15b), provided, at its end (17a,17b) distal relative to the rotation axis ("S") of the rotor (11), with a hammerhead (19), at least one pair of impact surfaces being defined in the hammerhead, wherein the electronic unit is programmed for causing the rotor housed in the cell to carry out at least two working cycles, a first working cycle wherein the rotor is driven in a first direction, clockwise or counter-clockwise, and, a second working cycle wherein the rotor is driven in a second direction opposite to the first direction, i.e. counter-clockwise or clockwise respectively.
