Product Details:

Homogenized bauxite refers to bauxite clinker with stable structure, performance and quality through homogenization process and appropriate high temperature calcination with high alumina bauxite as the main raw material. The development of homogenized bauxite (AI2O3 content 50% ~ 90%) can not only make full use of a large amount of idle low-grade bauxite, mixed-grade bauxite, crushed ore, and fine ore, and improve the quality of refractory raw materials and the utilization rate of bauxite resources . At the same time, the homogenization process can also improve mining efficiency, realize large-scale mechanized mining of high-alumina mines, realize that the composition, structure and performance of raw materials remain basically unchanged for a long time, ensure the stability of subsequent production processes, and improve production efficiency.

Features:

From the microstructure point of view, since the phase composition and uniformity of the distribution of bauxite clinker after calcining are closely related to the distribution of diaspore, kaolinite and impurities in the original ore, the composition of the material after the homogenization process is closely related The uniformity can be improved, and it will also have a certain impact on the phase composition of the clinker and its microstructure. The traditional high alumina bauxite clinker crystal distribution is very uneven, while the homogenized bauxite crystal grain size and distribution are relatively uniform, and small and uniform closed pores can also be seen. In addition, due to the high content of the homogenized bauxite glass phase, the glass phase containing Ti and Fe is significantly higher than that of the high bauxite clinker. At the same time, due to the homogenization process, the impurities originally concentrated in the bauxite will be dispersed. At high temperatures, a large number of glass phases are formed, which are distributed among the corundum grains, and the entire system is weakened, which may cause the overall high-temperature performance of the material to decrease. On the other hand, the glass phase is evenly distributed between the corundum grains. Since the liquid phase can promote sintering at high temperatures, the grains of homogenized alumina grow significantly larger and the structure is more compact.
