DEVICE AND METHOD FOR SEPARATION OF BULKY MATERIALS Russian patent published in 2009 - IPC B07C5/34 

FIELD: technological processes.

SUBSTANCE: device and method are suggested for separation of bulky materials with the help of blowing device equipped with blowing nozzles installed at drop section located downstream conveyor belt. Blowing nozzles are controlled by computer estimate facilities depending on signals from detectors of radiation that penetrates through flow of bulky material on conveyor belt, which is emitted by source of X-ray radiation and is detected by detector facilities. X-ray radiation that passes through particles of bulky material is filtered for separation into at least two spectra with different ranges of energy prior to position-sensitive detection of this radiation, which is integrated by range of energies, with the help of at least one detector facility.

EFFECT: reliable separation of undesirable inclusions from flow of classified material.
