An automatic sorting system identifying and sorting non-homogenous material includes a conveyor belt and an identification unit above the conveying surface for identifying material. The identification unit includes a projector projecting light downwardly onto material to be identified, which reflects light towards the identification unit. The identification unit includes a lens receiving the reflected light from the material, and a first processing unit linked to the lens for spectral analysis of reflected light captured by the lens to determine the nature of the material, and a second processing unit linked to the first processing unit for comparing spectral analysis results with data associated with different materials stored in a second processing unit database. A sorting unit links to the second processing unit and cooperates with the second end of the conveyor to sort material released from the second end depending on signals from the second processing unit.

System and method for identifying and sorting material

An automatic sorting system is for identifying and sorting non-homogenous material. The system includes a conveyor belt and an identification unit cooperable with the conveyor belt and placed above the conveying surface thereof for identifying material traveling therealong. The identification unit includes at least one projector for projecting a beam of light downwardly towards the conveying surface, at a given height above the conveying surface, and onto a given material to be identified, so that a portion of projected light may be reflected back from the given material and upwardly towards the identification unit. The identification unit also includes at least one lens positioned about the identification unit for receiving the portion of reflected light from the given material to be identified. The identification unit also includes a first processing unit operatively linked to the at least one lens for carrying a spectral analysis of the portion of reflected light captured by the at least one lens so as to determine the nature of the given material, and a second processing unit operatively linked to the first processing unit for comparing results of the spectral analysis with corresponding data associated to a variety of different materials stored in a given database of the second processing unit. The present system also includes a sorting unit operatively linked to the second processing unit and operatively cooperating with the second end of the conveyor so as to sort material released from the second end of the conveyor depending on signals received from the second processing unit.

An improved method of recovering recyclable materials from commingled recyclables is described as well as apparatuses for doing same. Ferrous materials recovery is achieved using the unique combination of a magnetic belt and a vibratory conveyor. Other materials are then separated with a light/heavy separator which uses finger screen, air knife, and vibratory means to separate glass from plastics and aluminum prior to conventional handsorting operations. Excess glass unsuitable for recovery is introduced into a trommel processing loop wherein contaminates are removed and the glass reduced to a particulate useful in the production of glasphalt and aggregate. Air emanating from the air knife is filtered in an improved gravity separator for reintroduction to the light/heavy separator.
