NuEvo air separator is designed to separate higher density materials such as stone and metal from the stream of material entering the hammer mill.

The separation of materials takes place when an airflow carries the material through the separator and over an opening. As the material is transported across the opening, gravity causes the heavier materials to fall into a trap below the separator. Lighter materials are transported across the opening and into the hammer mill below. An internal magnet removes metal from the product stream.
