LUMINESCENT SEPARATOR FOR OF MINERAL RAW MATERIALS DRESSING Russian patent published in 2005 - IPC

FIELD: mining industry; diamonds mining.

SUBSTANCE: the invention is pertinent to mining industry, in particular, to diamonds mining. The technical result of the invention is increase of electrical safety of a separator and reliability of its operation with simultaneous decrease of weight and dimensions of a power supply source for an X-ray tube. The separator contains a device of loading of a feed stock, a chute for delivery of the feed stock in a zone of detection of a required product, an X-ray tube connected to a source of its power supply, a photomultiplier, a block of control and data processing, a device for separation of a target product and a device for separate collection of the target and the end products. The source of power supply for the X-ray tube contains a transducer of mains voltage into low-voltage high-frequency voltage, a high-voltage transformer and a voltage multiplier. At that the high-voltage transformer and the voltage multiplier and also the X-ray tube are placed in a hermetic body filled in with a high-voltage insulating substance. One wall of the body has an opening, in which there is a fixed anode of the X-ray tube, which window for pass of the X-rays protrudes beyond the limits of the body.

EFFECT: the invention ensures electrical safety of a separator and reliability of its operation with simultaneous decrease of weight and dimensions of a power supply source for an X-ray tube.
