SYSTEM AND METHOD FOR GROUND MATERIAL CHARACTERISATION IN GRINDING SYSTEM Russian patent published in 2014 - IPC G01N33/10 G01N21/85 G01N1/20 G01N15/02 G01N15/14 B02C25/00 B02C4/28 B02C4/32 

FIELD: physics.

SUBSTANCE: system and method for ground material characterisation in a grinding system use an irradiation section through which at least a part of the ground material stream is fed and with irradiation means for irradiating the particles in the part of the stream with electromagnetic radiation; and a detection section for passage, having a detection means for detecting electromagnetic radiation emitted from the particles of the part of the ground material stream fed through the irradiation section The detection means comprises an imaging system and a colour image sensor for imaging the particles thereon using the electromagnetic radiation emitted by the particles. The colour image sensor comprises image elements for spectrally selective detection of the electromagnetic radiation imaged on the sensor image elements. The detection section comprises a luminous means or is made and arranged to detect particles of the ground material using a combination of transmitted and incident light.

EFFECT: high rate and accuracy of detecting properties of a stream of a grinding product.
