ABSTRACT:
Methods and systems for sorting particles entrained in a gaseous stream are disclosed. A representative system, among others, includes a particle scanner, a sorter, which is in pneumatic communication with the particle scanner, and a controller, which is in electrical communication with the particle scanner and sorter. The particle scanner is adapted to receive a gaseous stream and measure a characteristic of a particle entrained in the gaseous stream. The controller is adapted to classify the scanned particle according to the measured characteristic of the particle. The sorter includes an electrically controlled valve. Responsive to the particle being classified as belonging to a first category, the controller signals the valve to deflect the trajectory of the particle.A representative method, among others, for sorting particles entrained in a gaseous stream can be broadly summarized by the following steps: receiving particles in a gaseous stream; classifying a particle from the received stream of particles according to a property of the particle, wherein the particle is classified as belong to one category of a plurality of categories, and wherein the received particle has an initial trajectory; and responsive to the particle being classified as belonging to a first category of the plurality of categories, altering the trajectory of the particle.
