The rank of countries alumina bauxite storage is: Australia, The Republic of Guinea, Jamaica, China, and India. Rich reserves provinces in China are Shanxi, Guizhou, Guangxi and Henan province. Generally, alumina bauxite is used to produce alumina or aluminum.
Bauxite rotary kiln consists of steel shell, tire, drive gear, kiln hood, kiln seal, burner pipe. Kiln head guard and kiln tail return spoon are built-in block casting, so bauxite rotary kiln has many advantages like easy installation, high heat, corrosion and wear resistance. Kiln head-cold air cover ventilating with cold air makes kiln safer and more reliable by evenly cooling down kiln head, barrel and kiln mouth shield. More stable airflow profits from large volume kiln hood and split kiln door. Adopt the most advanced double seal technology in the world, which is radical friction maze seal and scales seal. This kind of seal form has a simple structure and is easy to maintain. The combustion device adopts a swirling four-channel pulverized coal burner with a burner pipe.
How to deal with the heating problem of roller tile on bauxite rotary kiln:The heating problem consists of heating thrust surface, heating roller tiles surface and both of them. To highlight the adjustment effect, push forward a roller tile in one pair while pulling back the other, but it cant suitable for the circumstance when the pair of them are both heatings. In case of the change of kiln centerline, you can adjust the wheel seat located in diagonal. After the adjustment, inspect the gap between thrust plate and roller tile and the temperature of roller tiles.

Calcinating quicklime business has existed for a long time in Chinese history. Until now, the usage of lime is larger and larger, the quality-demands are higher and higher in metallurgy, chemical industry, construction, and other sectors. For now, most Chinese adopts low-cost normal shaft kiln for calcinating lime, but shaft kiln has so many drawbacks, like its usage factor is lower than 50%; its energy consumption is high, coal usage above 160kg per ton lime; causes severe air pollution with diffuse smoke and dust and it is hard to collect dust because of its structure which seriously damages workers physical healthy cause their strong working intensity and direct operation in adding materials and discharge dust; quality of lime is not stable with more than 30% raw, overcooked and knotted rate.
Here is some good news, AGICO company provides newish environmental protection and energy-saving vertical lime kiln. Our company sells highly effective, environmental- friendly, automatic lime vertical kiln based on the advocate energy-saving and environment-friendly to bring back the blue sky concept. This newish shaft kiln has characters of energy-saving, environmental-friendly, high automation, low investment, short construction circle, which enjoys preference in large and medium-sized state-owned enterprises, private enterprises and self-employed enterprises.
Rotary kiln is the key equipment for the calcination of bauxite, clinker, limestone, etc.. According to the capacity of bauxite plant, clinker or cement plant, etc., we can help you select different size of rotary kiln, which is usually from 900mm to 4000mm.
Rotary kiln is mainly composed of kiln shell, refractory bricks, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The sealing effect is very good.
Material will be feed into kiln tail through chute in gas chamber. As kiln shell is inclined and it rotates slightly, material will move along round shell and will also move along shaft direction from kiln tail to kiln head. Material will be processed through pre-heat, decompose, calcined and will be feed into cooler. Fuel will be given through gas or coal burner at kiln head and will be combusted in kiln. Heat will be transferred to material by fire radiate, hot air flow, kiln brick transfer. The heat will heat and calcine material enough and make it final product.
1. Through technological innovation, our rotary kiln is designed with international leading wheel catch device, high precision plunger metering pump, high accuracy speed control valve and contact graphite block sealing device, etc.
2. In order to improve machinery automation, an industrial computer is used for showing the calcining condition, and a fluorescent screen is adopted for showing the simulated process flows. An infrared scanner is utilized for transmitting the calcining condition to the computer.
