Abstract: A material analysis and separation system equipped with a conveyor belt, X-ray source, X-ray detector, which has the X-ray source located in such a way that X rays penetrate the measured material over the entire width of the conveyor belt, and the radiation detectors consist of multiple radiation sensors located on the entire width of the belt, while the sensor system is equipped with devices that allow for data processing in dual energy (DE Dual Energy) or multi-energy (ME Multi Energy) X-ray analysis range. The system also includes a computer unit that controls the system rejecting material particles falling below the separation criterion threshold and devices receiving separated material fractions. The X-ray analysis system is equipped with a hyper-spectral analysis system in the range of infra-red radiation using a source of infra-red radiation (15) and hyper-spectral camera (19).

Abstract: Particle classifier (2) for separating solid particles in a flow of gas and particles (1) into two fractions depending on size by means of gravitation force, air resistance force and applied centripetal force. A mixture of gas and particles is charged well dispersed to a classifier inlet zone (3) from which the mixture is brought into contact with a rotor (6) in a first separation zone (5) having the form of a free rotor chamber. Gas and fine particles are allowed to escape through an upper outlet (9) while the coarse fraction of the particles is forced to pass through a second separation zone and subsequently to leave through a lower outlet (15).

Abstract: Apparatus of theforced air vortex type for classification of particulate material into a fine portion and a coarse portion, the apparatus comprising a truncated cone shaped upper section (101) comprising a separating wheel (111) rotating about a substantially vertical axis, a vertically arranged inlet pipe (106) for supplying a particulate material dispersed in an air flow, a conical feed distributor (107) having a tip end directed downwards and arranged concentrically with the inlet pipe (106) and the separating wheel, and a spiral shaped outlet (102) for removal of classified fine material dispersed in air, and a substantially truncated cone shaped lower section (103), the upper section of which exhibiting a secondary air inlet (105) arranged tangential to the circumference of the lower housing (103) to supply secondary air in a direction concurrently with the direction of rotation of the separating wheel (111) and a second outlet (104) for classified coarse particulate material.
