and a nozzle housing in which the nozzle is mounted and comprising an inlet opening on the side of the intake orifice and an outlet opening on the side of the discharge orifice, the nozzle moveably mounted in the nozzle housing such that the nozzle is moveable between an impact position and a home position; the nozzle assembly further comprising an elastic element mounted to work in conjunction with the nozzle and the nozzle housing such that the nozzle is held in the home position in an unloaded rest condition in which the nozzle is not subjected to an impact, and as a result of the force of an impact temporarily moves in the direction of the impact position; wherein the shredder housing is lined with one or more wear plates, the one or more wear plates being secured to the shredder housing by the one or more nozzle assemblies. ### Claim 2 (depends on 1) A shredder according to claim 1, wherein the nozzle housing comprises a bolt situated in an opening in the shredder housing and in an opening in the one or more wear plates, the nozzle housing further provided with a nut and washer. ### Claim 3 A shredder comprising a cutting drum and a shredder housing, the shredder housing comprising one or more nozzle assemblies mounted in a working zone of the cutting drum, the one or more nozzle assemblies each configured to atomise a liquid for preventing dust formation in the working zone of the cutting drum and the one or more nozzle assemblies each comprising: a nozzle with an intake orifice configured to receive the liquid, and a discharge orifice configured to atomise the liquid; and a nozzle housing in which the nozzle is mounted and comprising an inlet opening on the side of the intake orifice and an outlet opening on the side of the discharge orifice, the nozzle moveably mounted in the nozzle housing such that the nozzle is moveable between an impact position and a home position; the nozzle assembly further comprising an elastic element mounted to work in conjunction with the nozzle and the nozzle housing such that the nozzle is held in the home position in an unloaded rest condition in which the nozzle is not subjected to an impact, and as a result of the force of an impact temporarily moves in the direction of the impact position. ### Claim 4 (depends on 3) A shredder according to claim 3, wherein the home position is positioned closer to the cutting drum than the impact position, and is positioned such that the nozzle at the side of the discharge orifice does not protrude from the shredder housing when positioned in the home position. ### Claim 5 (depends on 3) A shredder according to claim 3, wherein the nozzle housing comprises a first stop against which the nozzle is pressed by the elastic element to hold the nozzle in the home position. ### Claim 6 (depends on 3) A shredder according to claim 3, wherein the nozzle housing comprises a second stop against which the nozzle is pressed in the impact position as a result of the force of an impact. ### Claim 7 (depends on 3) A shredder according to claim 3, wherein the elastic element comprises a spring. ### Claim 8 (depends on 3) A shredder according to claim 3, wherein the elastic element comprises an elastic bushing. ### Claim 9 (depends on 3) A shredder according to claim 3, wherein the elastic element comprises a hydraulic circuit with an accumulator or that the elastic element comprises a pneumatic circuit. ### Claim 10 (depends on 3) A shredder according to claim 3, wherein the liquid to be atomised is combined with a gas. ### Claim 11 (depends on 3) A shredder according to claim 3, wherein the elastic element comprises a first magnet mounted on the nozzle housing and comprises a second magnet mounted on the nozzle, the first magnet and second magnet comprising an opposing magnetic field. ### Claim 12 (depends on 3) A shredder according to claim 3, wherein the nozzle assembly comprises non-magnetic materials. ### Claim 13 (depends on 3) A shredder according to claim 3, wherein the nozzle housing is produced as a mounting element for the shredder. ### Claim 14 (depends on 13) A shredder according to claim 13, wherein the shredder housing is lined with one or more wear plates and the one or more nozzle assemblies are configured as mounting elements for these one or more of wear plates. ### Claim 15 (depends on 3) A shredder according to claim 3, wherein the discharge orifice is configured to atomise the liquid with a droplet size of less than 2 mm. ### Claim 16 (depends on 3) A shredder according to claim 3, wherein the outlet opening of the nozzle housing extends further towards the working zone of the cutting drum than the discharge orifice of the nozzle. ### Claim 17 (depends on 3) A shredder according to claim 3, wherein the outlet opening of the nozzle housing is provided with a slightly conical form that opens in the direction of the working zone. ### Claim 18 (depends on 3) A shredder according to claim 3, wherein the home position is positioned such that the nozzle, at the side of the discharge orifice, does not protrude or project from the shredder housing when positioned in the home position. ### Claim 19 (depends on 3) A shredder according to claim 3, wherein a diameter of the inlet opening on the side of the intake orifice is smaller than a diameter of the outlet opening on the side of the discharge orifice. ### Claim 20 A method of operating a shredder, the shredder comprising a cutting drum and a shredder housing, the shredder housing comprising one or more nozzle assemblies mounted in a working zone of the cutting drum, the one or more nozzle assemblies each configured to atomise a liquid for preventing dust formation in the working zone of the cutting drum and the one or more nozzle assemblies each comprising: a nozzle with an intake orifice configured to receive the liquid, and a discharge orifice configured to atomise the liquid; and a nozzle housing in which the nozzle is mounted and comprising an inlet opening on the side of the intake orifice and an outlet opening on the side of the discharge orifice, the nozzle moveably mounted in the nozzle housing such that the nozzle is moveable between an impact position and a home position; the nozzle assembly further comprising an elastic element mounted to work in conjunction with the nozzle and the nozzle housing such that the nozzle is held in the home position in an unloaded rest condition in which the nozzle is not subjected to an impact, and as a result of the force of an impact temporarily moves in the direction of the impact position; the method comprising: operating the nozzle assemblies in an active cycle, and operating the nozzle assemblies in a rinsing cycle, wherein the nozzle assemblies are rinsed with a fluid without additives during the rinsing cycle.
