Glass Applications
 Although glass batch sometimes flows freely, it also de-mixes readily via various particle size segregation [220K QuickTime video] mechanisms. This is a major contributor to quality control problems in glass making operations. Just changing the flow pattern in storage systems upstream of a furnace from funnel flow to a uniform, non-segregating mass flow pattern typically has a major benefit in providing well-mixed, consistent feed to a furnace. Whether you are producing optical fiber, light bulbs or wine bottles, we can show you how to increase the quality of your glass consistently.
Other types of flow problems such as arching (bridging) and ratholing can occur with some of the ingredients which make up batch. Cullet, for example, can be moist and often consists of large, irregularly shaped particles. Both of these characteristics can lead to flow irregularity. Even if you haven't encountered these problems yet, you eventually might, considering today's tough demands of increased production rates, tight quality control, and minimization of product loss. Flow problems during manufacture may result in off-spec material and, ultimately, dissatisfied customers, which will translate into lower sales and poor company image.
