Bauxite rotary Kiln

Bauxite rotary Kiln

Specifications:

Bauxite rotary kiln mainly by the rotary parts, bearing, gear, kiln hood, kiln head, sealing, burning device, etc.

Application Range:construction, building, metallurgy, mining, industrial garbage waste disposal,chemical and other relevant industries.

Applicable Materials:ceramic sand, clay, river sludge, coal ash, shale, furnace slag, dolomite, kaolin, bauxite and other relevant ores.

Advantages

Low energy consumption 

Our rotary kiln adopts reasonble running parameter; coal and electricity consumption can be 20% to 30% lower than common dryer. 

Simple structure and reasonable design,high automation level  

Simple and reliable operation; less labor force; stable process;At present, there is automatic bauxite rotary kiln which provides more convenience for customers.

Environmental protection and cause no pollution  

In terms of environmental protection, it causes less pollution, less maintenance and high running rate;

Flexible for heat source system  

Can be suitable for coal gas, coal powder, oil and many other kinds of fuels. 

Working Principle

Raw ores are fed into bauxite rotary kiln after passing through measuring scale, belt conveyor, stable bunker and air-locked valve. There is only stability bunker in order to save cost. Ores will heated first after entering bauxite rotary kiln. Raw ores will move toward the direction opposite from hot air in kiln. In heating area, raw ores will enter reduction area after reaching reduction temperature. The central temperature of flame in reduction area is controlled at about 1000 degrees. The hot air temperature in reduction area should be controlled at about 700 degree. Then, the hot air will react with reduced coal gas. After that, raw materials will enter cooling area and meet with coal gas which will be preheated. After being cooling, bauxite will be discharged out of the kiln. After being cooled, bauxite will enter storage.
