Aluminum is mined on a large scale as bauxite (containing about 50% Al 2O3·2H2O). Australia, Guinea and Brazil are the largest producers of bauxite ore in the world. The uses for aluminum in modern society are countless: cans and foils, kitchen utensils, building cladding, structural engineering applications where a strong, light, easily machined material is needed. Although its electrical conductivity is only about 60% that of copper per area of cross-section, but it is used in electrical transmission lines because of its lightness and price. Its various alloys are of vital importance in the construction of modern aircraft and rockets. Evaporated in a vacuum, it forms a highly reflective coating for both visible light and radiant heat. These coatings form a thin layer of protective oxide and do not deteriorate as do silver coatings. These coatings are used for telescope mirrors, decorative paper, packages and toys, and in many other applications.
Aluminum dressing equipment
Aluminum ore is mainly a diaspore ﹑ a boehmite and gibbsite. These are aluminum ores. Industrial grade aluminum ore indicators border, pit mining open-pit mining and the ratio of the Al-Si are 1.8 ~ 2.6, Al2O3 ≧ 40%; the lowest industrial grade, aluminum-silicon ratio of the open-pit mining ≧ 3.5, pit mining ≧ 3.8, Al2O3 ≧ 55% .
Aluminum ore primary crusher
Here we recommend to you Jaw Crusher as aluminum ore primary crusher. There are both double-toggle jaw crusher and single-toggle jaw crusher. Also there is more advanced European Jaw Crusher apart from ordinary jaw crusher.
Aluminum ore secondary crusher
For aluminum ore secondary crushing, you can choose cone crusher or impact crusher. What’s the difference is the final products’ shape. After crushed by impact crusher, the final products will be of good, cubic shape and without tensility and cranny. Therefore for highway and railway surface as well as water and electricity industry, we recommend to choose impact crusher.
Aluminum ore grinding machine: Ball Mill
Ball mill is the most traditional grinding machine in the aluminum ore grinding. With simple structure and reliable quality, ball mill is much popular in various minerals’ grinding.
