METHOD AND DEVICE FOR SORTING OUT OF STRUCTURES OF LOOSE MATERIALS Russian patent published in 2014 - IPC B07C5/342 

FIELD: process engineering.

SUBSTANCE: proposed method exploits the device for sorting out of separate structures 3.1 of loose materials 3 at conveyor 1 and controlled discharging fractionator 2. Sorting out criterion represents the distribution of structure 3.1 over height and the propagation of light from source 4. Light band 4.1 is projected across loose material conveyance direction onto conveyor plane 1 while structures 3.1 are displaced under light band 4.1. Light first part 4.1.1 is reflected by said structure. Light second part 4.1.2 enters the structure at inlet point 3.1.1 to get dissipated and to exit at point 3.1.2. Broadening B of light band due to dissipation is detected by chamber 9. Coherent areas are identified in buffered lines B_Z. Measured magnitudes are analysed and converted into attribute symbols. Depending on preset parameters of sorting out aforesaid discharging fractionator 2 is actuated.

EFFECT: perfected method.
