METHOD AND DEVICE FOR SELECTING GRAIN MATERIAL |
摘要 |
An ore sorting apparatus in which the ore to be sorted is selected for sorting according to their absorption of atomic radiation. Ore particles are passed beneath an X-ray tube 23 while being supported on a conveyor belt. X-rays passing through the ore particles impinge on a fluorescent screen 33. Images formed on the screen 33 are scanned by a scan camera 34 to provide sorting control signals in dependence upon the amount of radiation absorbed by the ore particles. |
