Shredder comprising one or more nozzle assemblies

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 one or more nozzle assemblies 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 one or more nozzle assemblies in an active cycle, and
• operating the one or more nozzle assemblies in a rinsing cycle, wherein the one or more nozzle assemblies are rinsed with a fluid without additives during the rinsing cycle;
• wherein the flow rate of the liquid used in the active cycle and the fluid without additives used in the rinsing cycle is determined in relation to a load on the shredder.
