13-05-2026 How calcined bauxite is made matters more than its alumina content. Small variations in raw ore, particle size, temperature control, and cooling can lead to unstable density, inconsistent porosity, and shorter refractory life. That’s why SEPPE uses rotary kiln processing – for consistent temperature control, batch stability, and reliable performance in refractory and abrasive applications. Need stable calcined bauxite?
