Whether you are producing optical fiber, light bulbs or wine bottles, we can help you improve the quality of your glass.

Most glass batch flows freely, but de-mixes readily via various segregation mechanisms. Other types of flow problems such as arching (bridging) and ratholing can occur with some of the ingredients that make up batch. Cullet, in particular, can be moist and often consists of large, irregularly shaped particles. Both of these characteristics can lead to flow irregularity. Providing well-mixed, consistent feed to the furnace can significantly improve the quality of your glass product.

Abrasive raw materials and cullet can contribute to wear of furnace feed bins, especially at the hopper connection. A failure at this point could have catastrophic consequences.

Whatever the problem may be, Jenike & Johanson can help by providing one or more of the following services.
