Abstract
Separation of glass from waste material by high tension techniques. The waste is sized to a range from 1/8 to 1 1/2 inches, dried to a moisture content less than 2%, air classified to remove low bulk density material, and subjected to magnetic separation to remove ferrous metal. The waste is then fed to the top of a rotating grounded drum and subjected successively to ion bombardment from corona discharge electrodes and to an electrostatic field from a static electrode. The glass remains pinned to the roll while other materials come off in the static field.
