X-ray separators are belt separators where material travelling on the belt passes between an X-ray transmitter source placed above the belt and a bank of LDA dual energy receiver placed under the belt that measures the level of absorption of wave lengths of every single piece constituting the material travelling on the belt that characterizes the atomic number of the material. The measurements are sent to a control unit which analyzes and computes them into separation decisions through the triggering of some pneumatic rejecter valves mounted on a bar positioned in front of the head pulley.
X-ray separators are used for applications like separating light from heavy metals in a mix of metals, typically used in combination and after eddy current separators (ECS) for the recovery of the non-ferrous metals that do not offer and easy response to ECS like:
Coal
Iron Ore
Diamonds
Auto Shredder Residue (ASR)
Glass scrap
Electronic scrap (WEEE)
Upgrade of Aluminium Scrap
