Calcium aluminate powder is an important ceramic raw material, which is widely used in construction, ceramics, electronics, aviation and other fields. Calcium aluminate powder is an important material that is widely used in construction, metallurgy, manufacturing and other fields. So, what is the production process of calcium aluminate powder?
Raw material preparation
The raw materials of calcium aluminate powder include aluminum hydroxide and calcium carbonate. These raw materials need to be screened, washed and dried to ensure that impurities and moisture are fully removed.
Mixing and preparation
After the raw materials are prepared, aluminum hydroxide and calcium carbonate need to be mixed in a certain ratio. During the mixing process, admixtures are added to control the reaction rate and improve the product quality.
High temperature reaction
After the mixture is prepared, the mixture is put into a high temperature furnace for reaction. This process needs to control the temperature, oxygen content and other factors to ensure the reaction process is normal.
Cooling and grinding
After the reaction of calcium aluminate powder, it needs to be cooled and ground. The product is cooled to room temperature and then mechanically ground to make it into fine powder form for subsequent applications.
Packaging and storage
After grinding calcium aluminate powder, it needs to be packed and put the product into a bag with good air permeability and try to avoid moisture, irradiation and vibration after packing to maintain its quality.
The main raw materials of calcium bauxite powder are bauxite and limestone. Firstly, bauxite and limestone are mixed according to a certain proportion, and then crushed to make its granularity even. The mixed powder is fed into the batching tank according to a certain proportion, and the batching machine will automatically batch according to the set proportion. The blended mixture is sieved and sent into the rotary kiln, which makes the mixture react chemically through high temperature baking to produce calcium aluminate powder. After firing, the calcium aluminate powder needs to be cooled, and the cooled calcium aluminate powder is then sieved into the standard calcium aluminate powder. The standard calcium aluminate powder is ground to make it finer and more uniform in quality. The roasted product will be crushed again to improve the fineness and uniformity of the product. Calcium aluminate powder production process needs to pay attention to the following issues: the selection and quality of raw materials: the quality of raw materials directly affects the quality of the product, and high-quality raw materials should be selected. Roasting temperature and time: The difference of roasting temperature and time will have an impact on the reaction products and should be adjusted appropriately. Crushing method and mode: The crushing method and mode will also directly affect the fineness and uniformity of the product, and a suitable crushing method and mode should be selected. The improvement of calcium aluminate powder production process can improve the output, quality and efficiency of the product and make certain contribution to the industrial development. It is packed and stored in a dry and ventilated warehouse. These are the several main aspects of the production process of calcium aluminate powder, which need to be operated in strict accordance with the standard to ensure the quality of the product. At the same time, during the production process, it is also necessary to strengthen the safety management to ensure the safety of production personnel. In conclusion, calcium aluminate powder is a material with wide application prospects, and understanding its production process can help to better apply the material.
