The nozzle motion system consists of a robot and a gantry. The robot is a six-axis type, and the gantry has X and Y axes. The positioning accuracy of the motion system is ≤±2mm, with a repeat positioning accuracy of ≤±2mm. The equipment is equipped with two vibrating screens: one for screening recovered media, and the other for screening media during the refill process. The soundproof enclosure consists of a base, structural frame, rock wool panels, sound-absorbing padding, acoustic panels, and a service access door. Fan noise control complies with GB12348-2008, with boundary noise ≤85dB(A).
