【Product introduction】
Refractory Calcined Bauxite is granulated material processed by high alumina bauxite clinker after crushing, sieving, iron removal and other processes. The usual specifications are (mm): 0-1, 1-3, 3-5, 5-8, 8-15, 15-50, 0-5, 0-50 (mm), specifications can also be processed according to customer requirements.
Refractory Calcined Bauxite is the main raw material for making advanced refractory materials, refractory bricks, casting materials, spraying materials, refractory furnace materials and other unshaped refractory materials.
Refractory Calcined Bauxite is divided into GAL40, GAL50, GAL60, GAL70, GAL75, GAL80, GAL85, GAL88 according to physical and chemical indicators.
