Ceramics, on the other hand, are commonly used to make abrasion resistant liners, insulation products (refractories), and filtering applications. If you are compacting your ceramic powders to achieve a higher density, we can help achieve consistent powder flow through your process.
Avoidance of inclusions and cording requires consistent flow of a well-mixed glass batch. If you are producing LCD screens, hand-held electronic displays, optical fibers, safety glass, light bulbs or beverage bottles, we can help you improve your glass quality.

Common Glass & Ceramics Industry Challenges
Most glass batch flows freely, but de-mixes readily via various segregation behaviors. Poor flow (arching and ratholing) can occur with some of the ingredients that make up the batch. Glass 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. Sand and cullet are highly abrasive and will cause wear of furnace feed bins, especially at the hopper connection. A failure at this point could have catastrophic consequences. Many ceramics are also highly abrasive given their alumina, silica, and oxide contents. Click here for a review of abrasive wear estimation with glass batch.
