Also known as alumina or bauxite bauxite, the main ingredient is alumina, alumina hydrate system containing impurities, is a earthy minerals. White or gray, because iron and brownish yellow or reddish. Density 3.9 ~ 4g / cm3, hardness 1-3, opaque, brittle. Extremely difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminum smelting, manufacture refractories. Bauxite kiln Features: 1, low energy consumption, than ordinary dome converter unit coal consumption can be reduced by 40%, good stability, strong market price advantage. 2, simple, reliable, and fewer personnel, process stability. 3, environmental pollution, low maintenance, running high. 4, applicable to gas, coal and fuel oil and other fuels. 5, can be upgraded to automatic control system more perfect and stable. Kiln in the production of leather is transformed from a liquid or semi-liquid adhesive layer is the same body of clinker and powder particles formed in the wall of the kiln. After the formation of the kiln skin lining for protection from the effects of high temperature and kiln per revolution caused by temperature changes. In addition, the kiln lining also protect the skin from friction material and chemical erosion, and can reduce heat loss kiln. Physical and chemical properties of the kiln temperature change rate and backing of a very close relationship, warming too fast, uneven expansion due to the backing of each part, can easily cause the lining of fragmentation, which will shorten the life of the lining . On the other hand, although the temperature is too slow for the protection liner very favorable, but production was adversely affected. Therefore, each one should be worked out according to the characteristics of rotary kiln lining itself a reasonable temperature curve, and slowly and evenly heating the heating curve according to the requirements.
