ABSTRACT:
Solid waste is sorted by passing it through a rotating hollow drum which has sets of extensions, called flights, from the interior wall of the drum, some sets of flights being separated from each other and from the entrance to the drum by blank sections along the drum wall. The first set of flights are knives, so that filled plastic waste bags are opened and emptied. The second set of flights are adjustable magnet strips, lifting and depositing ferrous material onto a conveyor. A ferrous scraper removes ferrous materials, for depositing onto the conveyor. The third set of flights are flexible lifters for lifting and depositing glass, grit and dirt onto another conveyor. A bar screen is positioned over the conveyor to screen out larger materials, clean the lifters, and to be cleaned by the lifters. The invention further includes a method of sorting solid waste comprising providing a rotary materials separator according to the invention, placing a stream of materials into the drum, and passing the stream through the drum.
