FIELD: mining industry. ^ SUBSTANCE: device has optical block, measuring channel with cell for sample of analyzed rock, channel for comparison with comparison cell, spherical mirrors system, which mirrors are optically connected to a set of light filters and infrared radiation source, measuring block and indication block. Into optical block, including infrared radiation source, also included is block for adapting optical filtration of rock with light filters mounting drive connected to its output. Comparison channel has n standard samples of mixtures of rocks with different minerals concentration values. Measuring block includes control block and infrared radiation detector, connected to amplification block, made in form of serially connected preamplifier and amplifier with automated amplification control, and output of amplification block is connected to signals synchronization block, made in form of measuring channel detectors and comparison channel, outputs of which are connected to optical density detecting block, connected to an ADC. Output of measuring channel detector is connected to control input of amplifier with automated amplification adjustment, output of ADC is connected to data input of microprocessor controller, data output of which is connected to indication block, and control output - to blocks for adapting standard samples of mixtures of rock and optical filtration of rock. ^ EFFECT: higher trustworthiness. ^ 4 dwg |
