Abstract
Disclosed herein is a metal sorting device including an X-ray tube, a dual energy detector array, a microprocessor, and an air ejector array. The device senses the presence of samples in the x-ray sensing region and initiates identifying and sorting the samples. After identifying and classifying the category of a sample, at a specific time, the device activates an array of air ejectors located at specific positions in order to place the sample in the proper collection bin.

11. A sorting device to distinguish materials of differing composition, comprising:
-
an X-ray tube, wherein the X-ray tube is in a fixed position; a first multi-energy detector having a photon counting rate of about 1 million counts per second, positioned in a fixed position to receive x-rays from the X-ray tube; a detector array positioned to receive x-rays from the X-ray tube, wherein the detector array has a spatial resolution of 0.02 inches per pixel; a microprocessor operationally connected to the first multi-energy detector and the detector array; a computer memory operationally connected to the microprocessor; an ejector controller operationally connected to the microprocessor; and at least one ejector attached to the ejector controller. - View Dependent Claims (12, 13, 14)
