Most glass batch flows freely, but it also de-mixes readily via various particle size segregation 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 that make up batch. Ratholing can greatly reduce the live capacity of a batch bin and lead to hardening of stagnant material. Cullet, in particular, can be moist and often consists of large, irregularly shaped particles. Both of these characteristics can lead to flow irregularity. 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.

If you are currently experiencing solids handling difficulties, Jenike & Johanson can help you eliminate them. Or, if you are designing a new process, we can utilize our industry-leading technology to help you avoid production mishaps, from silos to finished product.
