new bauxite rotary kiln in london

Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns, and lime kilns according to different materials processed. Cement kilns are mainly used for calcining cement clinker, which divided into two categories: dry process cement kilns and wet process cement kilns. Metallurgical and chemical kilns are mainly used for magnetizing roasting of iron ore-depleted ore in iron and steel plants in the metallurgical industry; oxidizing roasting of chromium and nickel-iron ore; refractory plant roasting high alumina vanadium ore and aluminum plant roasting clinker and aluminum hydroxide; And chrome ore powder and other minerals. Limekiln (ie active lime kiln) is used for roasting active lime and light-burning dolomite used in iron and steel plants and ferroalloy plants

Cement rotary kiln belongs to the category of building materials and equipment, it is a kind of lime kiln. 0.5mm tolerance cement rotary kiln means that the allowable error of rotary kiln shell is within plus or minus 0.5mm

Lime rotary kiln is also called roller rotary kiln. To make sure it’s air leakage coefficient is less than 10 percent, lime rotary kiln adopts advanced structure and reliable combined scale-like seal in both ends. It also uses composite refractory to reduce the loss of heat radiation

Shaft kiln, just as its name implies, is a kiln with erected shape. Shaft kiln with modern new technology has environmental protection function, energy-saving function, high mechanization, and high automaticity. It also has the ability to turn waste into wealth

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

The data survey found that the price of AGICO group’s rotary kiln will be about 600-1000 $cheaper than the prices offered by the merchants in other cities. The reasons for the analysis are as follows:

It is the main body of the rotary kiln (rotary kiln), usually 30 to 150 meters long, cylindrical, with 3 to 5 rolling circles in the middle. Most of the barrels are processed into 3-10 sections by the factory, and then welded by large trucks to the destination

On the contrary, the cooler and the preheater are devices that rapidly reduce the temperature of the rotary kiln after firing. It looks like a small rotary kiln, but the diameter is smaller and shorter

It is also called preheater, which is a device for preliminary heating of materials by the waste heat of exhaust gas discharged from the rotary kiln before the materials enter the rotary kiln. Most of them are vertical structures

【Raw materials】:  Bauxite, copper ore, iron ore, etc., in sand and stone yard, dry mortar, quartz sand. 【Processing capacity】: 90-1000t/d 【Application】:  used to calcining cement clinker and refractory materials;. 

  Bauxite rotary kiln is rotary cylinder equipment for burning various materials. It is widely used in economic fields. In cement industry, rotary kiln is the major equipment of burning raw cement into clinker; in chemical industry, rotary kiln can produce saleratus, burn phosphor fertilizer and barium sulphide, etc.; in metallurgy industry, it is used to produce aluminium hydroxide. It can be used for drying many kinds of materials limestone slag, coal powder , slag, clay stone. Its highest tempreture can reach 1600-1700 degree

  The kiln has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation, and convenient and reliable operation ; Therefore, the consumption of the coal and the electricity is lower than the common ones, while the production capacity is higher than 10-15%

rotary kiln for alumina is a widely used rotary kiln in

Rotary kiln for alumina combines with domestic advanced technology and foreign progressive technology. Rotary kiln for alumina has a lot of advantages concluding simple operation, advanced technology, reasonable structure, stable performance, etc

From a chemical point of view, rotary kiln for alumina’s working content is a process of reasonably disposing of heterogeneous heat and mass transfer of solid and gaseous media. Those processes require both high operating technique and a lot of changing factors. So, it is more difficult in operating this process than heterogeneous heat or mass transfer process between gaseous and liquid. Alumina rotary kiln has a small inclination angle to the horizontal line. Raw materials flip up and down then move forward upon the inner wall with the rotation of kiln. Materials’ rotation keeps the air in the kiln contact with them to proceed with heterogeneous heat transfer and mass transfer operations
