Glass Cullet - Processing Solutions

Materials:Glass Cullet, Pigments, Stains

Problem:

Iron (in free form) is an enemy to the production of electrical insulators. A major Indian manufacturer of glass insulators, knew that iron-impregnated insulators could not withstand the very high voltage required within television picture tubes. The sources of contamination were found to be the cullet, or re-ground glass required for production, as well as the coloring agents, called pigments or stains.

Solution:

The customer eliminated ferrous contamination by adding a Model P Grate Magnet to the cullet line, as well as a Liquid Line Trap to the pigment slurry.

Problem:

Broken glass, or cullet is needed for efficient operation of glass furnaces. The Thatcher Glass Company in Wharton, NJ, USA was getting too many rejects of their finished new bottles due to unwanted pieces of iron in the cullet.

Solution:

An Eriez Suspended Electromagnet and Magnetic Pulley were installed for a one-two separation. The suspended magnet removed 97 percent of the tramp iron, while the pulley removed the rest according to Richard Smith, Melting Manager.
