Abstract: A waste grinding apparatus (101) including a rotor having a central body (13) defining at least one radial vane (15a, 15b), provided, at its end (17a, 17b) distal relative to a rotation axis (“S”) of the rotor (11), with a hammerhead (19) in which a first, knocker impact surface (21) adapted to operate when the rotor (11) rotates in a first, clockwise or counter-clockwise direction, and a second, wedge-shaped impact surface (23) adapted to operate when the rotor (11) rotates in a second direction opposite to the first direction, are defined.

Abstract: A plant for the processing of waste includes an outer housing and a grinding cell, in which a grinding chamber is defined having at least one inlet opening for introducing the waste to be processed, and at least one outlet opening for discharging the material resulting from waste processing. The openings are associated with a corresponding closure element, adapted to isolate the grinding chamber from the outer environment. The outer housing defines therein a space receiving the grinding cell and integrally surrounds the grinding cell, and in which the space is accessible through at least one door.

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.
