The use of a dual energy X-ray scanning imaging system to capture images of freely falling/sliding groove falling materials results in higher signal-to-noise ratio, wider particle size adaptability, and a lower limit of sorting particle size as low as 6mm.

The material falls freely into the chute after being discharged from the vibrating screen, with no physical contact throughout the process and no risk of mechanical failure; The spray system is horizontally arranged and not easily clogged. Material falling to the viewing point can accelerate to 3m/s, and the execution point speed is about 5m/s. Under the same conditions, the processing capacity of the belt type intelligent dry sorting machine is 30% higher.
