FIELD: mining industry. SUBSTANCE: device has base, transportation and discharge hollows provided with hatches in upper part, reversing transportation arteries, hollow perforated members with proximate analyzers, communicating transport mechanism, and finished product assembly conveyer. Novelty consists in that device has guide rounding combs installed between hatches. Formed between adjacent combs is hollow. Perforated member with proximate analyzer is accommodated in said hollow. EFFECT: increased ore quality due to improved accuracy of its proximate analysis by reduced distortion of its results in ore decreased losses. 2 dwg
