Refractory Industry
There isn’t too much in our daily lives than are not impacted by refractories. From the glass containers we drink from or store our foods, the fuel that is used to power our vehicles and farm machinery, the roads and bridges we use for transportation, to the high end modern technologies we enjoy, refractories play a major role.
Christy Minerals mines and processes Missouri Fireclay from some of the highest quality deposits in the world. We start by selectively mining the clays and sorting the best quality using both state of the art analytical equipment and qualitative methods supported by years of experience to assure a consistent finished product for our customers applications. Next this clay is transported to our High Hill, MO manufacturing plant and calcined in our rotary calcining kiln under controlled conditions to maximize both mullite formation and density. Once the quality has been approved, the Kiln Run is stored under roof for shipment directly to customers with their own crushing and screening equipment or crushed and screened to order in our facility.
Our Calcined Flint Clay is available in a wide range of sizes from coarse graded aggregates to fines produced in one of our two ball mill systems. We are located close to a major interstate for easy truck transportation, close to the Missouri and Mississippi Rivers for transportation by barge and serviced by the Norfolk and Southern Railroad for rail transport.
Christy Minerals Calcined Flint Clay is used in refractory castable, refractory brick, mortar, plastics and preshaped refractory pieces. Calcined Flint Clay is available in bulk, 50lb bags, 100lb bags, or supersacks.
