ANALYSIS OF SOLID MINERAL SAMPLES FOR EFFICIENCY OF LUMPY LUMINESCENT SORTING AND DEVICE TO THIS END Russian patent published in 2015 - IPC B03B13/00 B07C5/34 G01N21/00 

FIELD: mining.

SUBSTANCE: proposed method comprises consecutive feed of lumps in control zone for irradiation and registration of wanted signal. Said lumps are fed in said zone in fixe path with lump sides' fixation relative to wanted signal registration radiation directions with setting of unlimited control zones passages with variable irradiation and registration parameters. Proposed method is realized with the help of the device including the case, lumps feeder, irradiator and radiation receiver as well as control device. Irradiator and receiver incorporate their drives. Lumps feeder is composed of multisection trick displacing on guide shaft and provided with specimen fastener and driven by step motor with the help of drive belt. Microprocessor-based control device controls the speed of passing by of control zone, operation of irradiator, receiver and their drives as well as a series of logically related experiments with specimens runs through control zone.

EFFECT: perfected process.
