MULTI-CHANNEL X-RAY SEPARATOR Russian patent published in 2011 - IPC B03B13/06 

FIELD: process engineering.

SUBSTANCE: invention relates to ore dressing and may be used in lumpy radiometric separation of ore. Separator includes multi-channel ore lump vibration handler, measuring radiator, X-ray radiator with collimator, X-ray detectors and actuators arranged in each channel and connected with control system, as well as concentrate receiving hoppers and separation tails. Vibration handler is equipped with lump trajectory shaper in the form of gravity conveyor. Gravity conveyor repeats the profile of handler chutes. And is mounted on the side of handler unloading end at blunt angle to the latter and secured on the frame. Measuring radiator is arranged on opposite side of lump free fall zone while X-ray detectors are made up of self-contained receivers. Each said receiver comprises X-ray detector and channel actuator control signal generator. Actuators are made up of air blow-out nozzles, two nozzles per one channel arranged in line with spacing equal to that of chutes and connected to said channel actuator control signal generator. Slit of X-ray radiator collimator, said receivers and blow-out nozzles are arranged in line.

EFFECT: higher accuracy of determining characteristics of signal lump in flight and faster operation of actuators.
