Because raw material and in-process quality control are extremely important in the production of fused minerals, quality control is vital. C-E Minerals is ISO certified, and has been since 1993. It assures that every rail car delivery of quartz sand meets stringent quality levels for size, PH, magnetic iron and chemistry and requires a formal vendor certificate of analysis before any raw material is accepted.
The production of fused silica begins with the fusion process. The furnace’s rapid rotation causes the melting sand to form an opening inside the metal shell, and as heat is applied, the ingot fuses from the inside-out. After fusion is completed, the ingot is removed from the furnace and taken to a covered cooling area.
Once cooled, the ingot is stripped of its crust and transported to the primary crushing system.
At this point, the crushed material is directed to either a series of crushing and screening operations for grains, or to a weigh feeder and continuous ceramic ball or batch mill for the production of fused silica powders.
Teco-Sphere® powders are produced using a proprietary process that forms each particle into a spherical shape, providing a material with high flow and minimal surface area.
Contact C-E Minerals for specific sizes and available packaging. Modern warehousing and shipping capabilities, combined with superior products, make Teco one of the world's leading suppliers of fused silica.
