Calcined Bauxite
Description
The main firing equipment for bauxite clinker products are rotary kiln, shaft kiln, shuttle kiln and down draught kiln ,Because of the different structure and operation mode of each kiln, the firing temperature and physicochemical index of the products are different, which respectively meet different industrial uses.
Normally, bauxite is calcined at a high temperature of 1400 to 1600 degrees in the kiln, and at a temperature higher than the temperature of the secondary mullite phase transformation, resulting in the formation of the mullite corundum phase with higher purity and density, with good thermal shock resistance and other superior physical and chemical properties, widely used in aluminum smelting, metallurgy, chemical, refractories and other industries. the calcined bauxite clinker has been tested and classified into different grades according to the content of alumina, then through the crushing system, processing into particles and fine powder to meet the actual needs of different customers.
At present, our calcined bauxite clinker products have been sold all over the world, relying on China's high-quality aluminum ore resources, advanced production technology, scientific management system, quality and cheap products and thoughtful service. Has been recognized by the vast number of customers, welcome to consult and negotiate at any time, we will achieve your satisfaction with high quality products and services.
