Abstract
An air material separator may be used to separate scrap from a conveying air flow while having a relatively low weight and short height so that the separator may be positioned within today's single-story manufacturing or processing facilities. The air material separator of the invention includes a generally cylindrical inlet chamber having a spiral wall that directs the inlet flow circumferentially and downwardly. An outlet chamber is positioned below the inlet chamber and includes a conical, perforated wall that allows the conveying air flow to escape through the perforated wall. The scrap carried by the conveying air flow cannot pass through the perforated wall and moves down and out an outlet at the bottom of the conical wall. The overall height of the device is substantially less than prior art air material separators.
