The hamos KWS separates conductive from non-conductive materials. The mixture is introduced via vibrating conveyor to a rotating metal drum. Inside this process is also a 35,000-volt electrode that is constantly charging the materials. The metal loses its charge very quickly to the drum and is ejected by the rotational momentum, while the plastic loses its charge much slower, allowing for a very clean separation of the different materials.

For proper processing, hamos systems require a few different parameters to work best. There must be two distinct and separate materials in the mixture (no composites), the material must be dry, dust free, and have a particle size of ~10mm.
