Use Of Calcined Bauxite And Performance Advantages Of Bauxite Rotary Kiln

Bauxite, also known as bauxite or bauxite, has an extremely complex composition and is the general name of water-bearing alumina ores with different geological sources.
Bauxite is difficult to melt and insoluble in water, but it is soluble in sulfuric acid and sodium hydroxide, and is often used in the smelting industry, mainly for the manufacture of refractory materials, and is also widely used in the construction field, so the market demand for this material is relatively large.
The significance of bauxite calcination:
The significance of bauxite calcination is to make bauxite widely used. After crushing and grinding, bauxite can be made into powder, fast and granular clinker through calcination process, which can stabilize the performance of products and improve the value of materials to a greater extent.
Bauxite rotary kiln is an important production line equipment for bauxite calcination.
Bauxite high-temperature calcination equipment is a professional equipment for processing and calcination, also known as bauxite rotary kiln, which is popular in the field of aluminum processing due to its high quality of calcined products, few operational failures, safe production and short economic recovery cycle.
Use of calcined bauxite:
1. Precision casting. The bauxite clinker is processed into fine powder and made into casting mould, which can be used for precision casting, such as instruments, communications and other departments.
2. Used for refractory products: high alumina clinker has a fire resistance of 1780 ℃, strong chemical stability and good physical properties.
3. Aluminum silicate refractory fiber: light weight, high temperature resistance, good thermal stability, low thermal conductivity, small thermal capacity, and mechanical impact resistance. It can be used in many industries such as steel, electronics, petroleum, chemical industry, etc.
4. Using magnesia and bauxite clinker as raw materials and adding appropriate binder, the effect of pouring the integral barrel lining of steel ladle is very good.
5. It can be used to manufacture bauxite cement, abrasive materials, ceramic industry and chemical industry, and various aluminum compounds.
Performance advantages of bauxite rotary kiln:
1. The pipeline of bauxite rotary kiln is high-pressure steam, which adopts low temperature and slow heat exchange, with large heat exchange area, constant temperature of heat exchange medium, and easy to control the calcination process.
2. The bauxite rotary kiln has large volume, large processing capacity, good drying and calcination effect and strong product stability.
3. One-step method simplifies the process flow, drying and calcination are continuously completed in the same equipment, and the control is simple, reducing the supporting equipment and control links.
4. Automatic production, feeding operation, calcination to finished product transportation, and setting of rotary kiln operation monitoring, regulation, startup emergency signal are all controlled by the PLC control system in the central control room.
5. Clean combustion, in line with environmental protection emission standards. The heat source can come from natural gas, liquefied gas, coke oven gas, generator gas, light diesel oil and electricity.
