Abstract
A cross-flow air separation system comprises a conveyor configured to project material out over an end of the conveyor generally along a trajectory path into a far receiving bin. An optical sensing system is configured to identify particular objects in the projected material. A first air ejection system is configured to generate a first airstream that ejects the identified objects from the trajectory path into a second near receiving bin. A second cross air current system is configured to generate a second airstream that reduces air resistance for the materials projected along the trajectory path. The second airstream reduces certain aeronautic phenomena that would cause some of the projected materials to unintentionally fall into the wrong receiving bin, thus creating a higher purity/less contaminated materiel stream into the near bin.
