1.Introduction of Bauxite:
The main component of bauxite is alumina, which is hydrated alumina containing impurities and a kind of earthy mineral. The density of bauxite is 3.45g/cm3 and hardness is 1-3. Our company mainly supply bauxite clinker. It is also known as high alumina clinker. Bauxite clinker is mainly used for high alumina refractory products. The various high alumina brick is produced by bauxite clinker, which is widely used in the metallurgical industry and other industrys, especially in the top of electric furnace, blast furance and hot blast stove.

Andalusite is a superior high-alumina refractory material, with high temperature stability, chemical resistance, heat resistance, strong impact resistance, high thermal mechanical strength characteristics. The color of andalusite is gray, pink and red-brown. Heating to 1300, Andalusite will turn into mullite, which is one of the raw materials to produce advanced refractories.
