Bauxite has high thermal stability, high mechanical strength and good resistance to molten slags. Sinabuddy is able to supply three kind of kilns for calcination process: Rotary kiln Bauxite, Round kiln Bauxite, shaft kiln Bauxite, and all kinds could be with Al2O3 contents from 75% to 90%.Bauxite is widely used for Refractories, Aluminium metallurgy, Precision casting or Investment casting, the molten steel ladle, Aluminium silicate refractory fiber, bauxite cement, etc. It also can be used in Road systems for its high-friction and anti-skid properties.
